Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a U.S. National Phase patent application of International Patent Application No. PCT/EP2015/069439, filed Aug. 25, 2015, which claims priority to Danish Application No. PA201400473, filed Aug. 25, 2014, each of which is hereby incorporated by reference in the present disclosure in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention provides a passive inhaler comprising compositions which comprises cannabidiol or a derivative or a variant thereof. Further, the device comprises a carrier. The device is suitable for delivery of CBD as a vapor to the oral cavity and to the lungs. It is a characteristic of the device that it is able to deliver sufficient amounts of CBD to the oral cavity, for it to be delivered to the brain in a quantity which is relevant in order to accomplish a pharmacologic effect of the CBD in the brain. The passive inhaler device is able to deliver CBD to the brain for use in various applications. In some instances, the inhaler comprises cannabidiol or a derivative or a variant thereof, or THC or a derivative thereof or a terpene or a combination of any one of those, for delivery as a gas, or a vapor or an aerosol or a mist into the oral cavity for uptake and transport to the brain, for the treatment, prevention or alleviationment of various conditions, such as pain, anxiety, depression or plaque related diseases. In some instances, the inhaler comprises flavours, which may in some embodiments be in the form of terpenes, for delivery to the brain for enhancing transport of other substances such as in example nutrients or active pharmaceutical ingredients (API) across the blood brain barrier. 
       BACKGROUND OF THE INVENTION 
       [0003]    There is a need for novel or improved treatments for a number of brain diseases, and additionally a need for enhancement of delivery of otherwise effective API across the blood brain barrier in order to facilitate the action of such API on their brain targets, by making the API available to have effect on the target on site in the brain. The present invention provides means to improve treatment of such diseases, and to enhance delivery locally to the brain of API which are present in the blood circulation but unable to pass the blood brain barrier in sufficient amount. 
         [0004]    Pain 
         [0005]    Pain in various forms and origin affects the lives of many people every day. Several types of pain exist, including neuropathic pain, nociceptive pain and psychogenic pain. 
         [0006]    Neuropathic Pain 
         [0007]    Neuropathic pain is caused by damage to or dysfunction of the nerves, spinal cord, or brain. 
         [0008]    Neuropathic pain may be felt as burning or tingling or as hypersensitivity to touch or cold. Causes include compression of a nerve (for example, by a tumor, by a ruptured intervertebral disk, or as occurs in carpal tunnel syndrome), nerve damage (for example, as occurs in a metabolic disorder such as diabetes mellitus), and abnormal or disrupted processing of pain signals by the brain and spinal cord. Processing of pain is abnormal in phantom limb pain, postherpetic neuralgia, and complex regional pain syndrome. 
         [0009]    Phantom Limb Pain 
         [0010]    Pain seems to be felt in an amputated part of the body, usually a limb. It differs from phantom limb sensation—the feeling that the amputated part is still there—which is much more common. Phantom limb pain cannot be caused by a problem in the limb. Rather, it must be caused by a change in the nervous system above the site where the limb was amputated. But the brain misinterprets the nerve signals as coming from the amputated limb. Usually, the pain seems to be in the toes, ankle, and foot of an amputated leg or in the fingers and hand of an amputated arm. The pain may resemble squeezing, burning, or crushing sensations, but it often differs from any sensation previously experienced. For some people, phantom limb pain occurs less frequently as time passes, but for others, it persists. Massage can sometimes help, but drug therapy is sometimes necessary. 
         [0011]    Postherpetic Neuralgia 
         [0012]    This disorder results from herpes zoster (shingles, which causes inflammation of nerve tissue), but occurs only after shingles resolves (see Postherpetic Neuralgia). What causes postherpetic neuralgia is unknown. The pain is felt as a constant deep aching or burning, as a sharp and intermittent pain, or as hypersensitivity to touch or cold. The pain may be debilitating. Pain relievers and other drugs may be required, but no treatment is routinely effective. 
         [0013]    Complex Regional Pain Syndrome 
         [0014]    This chronic pain syndrome is defined as persistent burning pain accompanied by certain abnormalities that occur in the same area as the pain. Abnormalities include increased or decreased sweating, swelling, changes in skin color, damage to the skin, hair loss, cracked or thickened nails, muscle wasting and weakness, and bone loss. This syndrome typically occurs after an injury. There are two types:
       Type 1, which used to be called reflex sympathetic dystrophy, results from injury to tissues other than nerve tissue, as when bone is crushed in an accident or when heart tissue is damaged in a heart attack.   Type 2, which used to be called causalgia, results from injury to nerve tissue. Sometimes complex regional pain syndrome is made worse by activity of the sympathetic nervous system, which normally prepares the body for stressful or emergency situations—for fight or flight. For this reason, doctors may suggest treatment with a sympathetic nerve block (see Pain:Anesthetics). Physical therapy and drugs may also help.       
 
         [0017]    Nociceptive Pain 
         [0018]    Nociceptive pain is caused by an injury to body tissues. 
         [0019]    The injury may be a cut, bruise, bone fracture, crush injury, burn, or anything that damages tissues. This type of pain is typically aching, sharp, or throbbing. Most pain is nociceptive pain. Pain receptors for tissue injury (nociceptors) are located mostly in the skin or in internal organs. 
         [0020]    The pain almost universally experienced after surgery is nociceptive pain. The pain may be constant or intermittent, often worsening when a person moves, coughs, laughs, or breathes deeply or when the dressings over the surgical wound are changed. 
         [0021]    Most of the pain due to cancer is nociceptive. When a tumor invades bones and organs, it may cause mild discomfort or severe, unrelenting pain. Some cancer treatments, such as surgery and radiation therapy, can also cause nociceptive pain. Pain relievers (analgesics), including opioids, are usually effective. 
         [0022]    Psychogenic Pain 
         [0023]    Psychogenic pain is pain that is mostly related to psychologic factors. 
         [0024]    When people have persistent pain with evidence of psychologic disturbances and without evidence of a disorder that could account for the pain or its severity, the pain may be described as psychogenic. However, psychophysiologic pain is a more accurate term because the pain results from interaction of physical and psychologic factors. Psychogenic pain is far less common than nociceptive or neuropathic pain. 
         [0025]    Any kind of pain can be complicated by psychologic factors. Psychologic factors often contribute to chronic pain and may contribute to pain-related disability. In such cases, the pain, disability, or both usually have a physical cause, but psychologic factors exaggerate or enhance the pain, making it worse than what most people with a similar physical disorder experience. For example, people with chronic pain know it will recur and may become fearful and anxious as they anticipate the pain. These emotions make them more sensitive to pain. Sometimes doctors describe chronic pain that is worsened by psychologic factors as a chronic pain syndrome. 
         [0026]    The fact that pain is caused or worsened by psychologic factors does not mean that it is not real. Most people who report pain are really experiencing it, even if a physical cause cannot be identified. Doctors always investigate whether a physical disorder is contributing to pain. 
         [0027]    Pain complicated by psychologic factors requires treatment, often by a team that includes a psychologist or psychiatrist. Treatment for this type of pain varies from person to person, and doctors try to match the treatment with the person&#39;s needs. For most people who have chronic psychogenic pain, the goals of treatment are to improve comfort and physical and psychologic function. Doctors may make specific recommendations for gradually increasing physical and social activities. Drugs and nondrug treatments—such as biofeedback, relaxation training, distraction techniques, hypnosis, transcutaneous electrical nerve stimulation (TENS), and physical therapy—may be used. Psychologic counseling is often needed. 
         [0028]    The present invention also provides treatments for alleviation of Complex Regional Pain Syndrome (CRPS), which is a disease of unknown cause, but which exhibit severe pain to touch, swelling of e.g. legs or arms, skin and or hair and or nail changes temperature changes in affected part of the body, muscle weakness, tremors and dystonia. 
         [0029]    Present Treatment Modalities for Pain 
         [0030]    There is a need for improved treatment modalities for different kinds of pain. Fast onset of action is important, but also treatments capable of adding to effects of existing treatments. Further, safety and tolerability is important. In example, cannabidiol is presently in some countries used to treat pain in patients suffering from multiple sclerosis. However, although cannabidiol (CBD) has some effect on such patients when administered orally in capsules, or by other means which make it systemically available, it is not sufficient to fully alleviate the pain. Furthermore, some patients do not respond to CBD when administered systemically or orally by ingestion of CBD in capsules. The present invention provides a means for delivering CBD to have improved speed of action, and also to add on the effect of systemically administered CBD, and further to treat pain in CBD non-responders (when administered systemically (orally or by other means which make it available in the blood circulation)). 
         [0031]    The administration of CBD according to the present invention, may be in combination with existing treatments for pain, which is claimed. 
         [0032]    Present Treatment of Anxiety and Depression 
         [0033]    There is a need for improved treatment modalities for anxiety and depression, both speed of action, less side effects and more efficient effects on the diseases. De Mello Schier et al. (CNS Neurol Disord Drug Targets, 2014; 13(6): 953-60) describe in a review that CBD has been tested in animal models of anxiety and depression and exhibited both anti-anxiety and antidepressant effects. 
         [0034]    The present invention provides an improved method for delivering CBD to the brain in small but pharmacologically relevant dosages. The CBD is delivered fast by inhalation, to provide a fast action, and in small dosages to reduce side effects, but is still effective on brain targets. 
         [0035]    Treatment of Epilepsy 
         [0036]    There is a need for further medications for treatment of epilepsy, as present treatments can control seizures in about 70% of patients. Furthermore, side effects are common for most epilepsy drugs on the market presently. Therefore, there is a need for improved methods for treating epilepsy. 
         [0037]    Treatment of Motion Sickness 
         [0038]    Motion sickness or kinetosis, or other causes for vomiting, has a need for improved medicines which are convenient for the patient to administer at any time or location. In example, swallowing a pill may be inconvenient, whereas inhaling a substance may be done without a neet to have water available. Therefore, the present invention provides a more convenient and safe anti-emetic drug for use in treating or preventing vomiting and the feeling of motion sickness. Further, safe, effective and convenient methods of treating side effects of opioid analgesics, side effects of general anaesthetics, side effects of chemotherapy, severe cases of gastroenteritis and morning sickness are also needed. 
         [0039]    Treatment of COPD 
         [0040]    Chronic obstructive pulmonary disease (COPD) is the name for a collection of lung diseases including chronic bronchitis, emphysema and chronic obstructive airways disease. 
         [0041]    People with COPD have difficulties breathing, primarily due to the narrowing of their airways, this is called airflow obstruction. 
         [0042]    Symptoms of COPD 
         [0043]    Symptoms of chronic obstructive pulmonary disease (COPD) usually develop over a number of years, so you may not be aware you have the condition. COPD does not usually become noticeable until after the age of 35 and most people diagnosed with the condition are over 50 years old. 
         [0044]    Symptoms include:
       increasing breathlessness when exercising or moving around   a persistent cough with phlegm that never seems to go away   frequent chest infections, particularly in winter   wheezing       
 
         [0049]    Middle-aged smokers and ex-smokers who have a persistent chesty cough (especially in the morning), breathlessness on slight exertion or persistent coughs and colds in the winter should see their GP or practice nurse for a simple breathing test. 
         [0050]    If you have COPD, the airways of the lungs become inflamed and narrowed. As the air sacs get permanently damaged, it will become increasingly difficult to breathe out. 
         [0051]    It is thought there are more than 3 million people living with the disease in the UK, of which only about 900,000 have been diagnosed. This is because many people who develop symptoms of COPD do not get medical help because they often dismiss their symptoms as a ‘smoker&#39;s cough’. 
         [0052]    COPD affects more men than women, although rates in women are increasing. 
         [0053]    Present Treatment Modalities for COPD 
         [0054]    Although the damage that has already occurred to your lungs cannot be reversed, you can slow down the progression of the disease. Stopping smoking is particularly effective at doing this. 
         [0055]    Treatments for COPD usually involve relieving the symptoms with medication, for example by using an inhaler to make breathing easier. Pulmonary rehabilitation may also help increase the amount of exercise you are capable of doing. 
         [0056]    Surgery is only an option for a small number of people with COPD. 
         [0057]    While there is currently no cure for COPD, the sooner the condition is diagnosed and appropriate treatment begins, the less chance there is of severe lung damage. 
         [0058]    Symptoms of COPD are often worse in winter, and it is common to have two or more flare-ups a year. A flare-up (also known as an exacerbation) is when your symptoms are particularly bad. This is one of the most common reasons for people being admitted to hospital in the UK. 
         [0059]    Other signs of COPD can include: weight loss, tiredness and fatigue and swollen ankles. 
         [0060]    Causes of COPD: 
         [0061]    Smoking is the main cause of COPD and is thought to be responsible for around 90% of cases. The lining of the airways becomes inflamed and permanently damaged by smoking and this damage cannot be reversed. 
         [0062]    Up to 25% of smokers develop COPD. 
         [0063]    Exposure to other people&#39;s smoke increases the risk of COPD. 
         [0064]    Exposure to certain types of dust and chemicals at work, including grains, isocyanates, cadmium and coal, has been linked to the development of COPD, even in people who do not smoke. 
         [0065]    The risk of COPD is even higher if you breathe in dust or fumes in the workplace and you smoke. 
         [0066]    According to some research, air pollution may be an additional risk factor for COPD. 
         [0067]    However, at the moment it is not conclusive and research is continuing. 
         [0068]    Present Treatment of COPD 
         [0069]    There is no cure for COPD at present. Avoidance of exposure to the most important causes of COPD is presently the most effective treatment. Furthermore, certain medicines such as bronchodilators and also corticosteroids are used, depending on the severeness of the disease. 
         [0070]    Lung Cancer 
         [0071]    There are two major types of lung cancer, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Staging lung cancer is based on whether the cancer is local or has spread from the lungs to the lymph nodes or other organs. Nonsmall cell lung cancer which accounts for about 85% of lung cancers is divided into three types of tumors: adenocarcinoma, squamous cell carcinoma and large cell carcinomas. Nonsmall cell lung cancer is staged in four stages depending on the degree of spreading: 
         [0072]    Stages of Non-Small Cell Lung Cancer 
         [0073]    Stage I: The cancer is located only in the lungs and has not spread to any lymph nodes. 
         [0074]    Stage II: The cancer is in the lung and nearby lymph nodes. 
         [0075]    Stage III: Cancer is found in the lung and in the lymph nodes in the middle of the chest, also described as locally advanced disease. Stage III has two subtypes:
       If the cancer has spread only to lymph nodes on the same side of the chest where the cancer started, it is called stage IIIA.   If the cancer has spread to the lymph nodes on the opposite side of the chest, or above the collar bone, it is called stage IIIB.       
 
         [0078]    Stage IV: This is the most advanced stage of lung cancer, and is also described as advanced disease. This is when the cancer has spread to both lungs, to fluid in the area around the lungs, or to another part of the body, such as the liver or other organs. 
         [0079]    Small cell lung cancer accounts for 15% of lung cancers in the US, it is staged in two stages: 
         [0080]    Limited stage where the cancer is found only on one side of the chest involving only one part of the lung and nearby lymph nodes. 
         [0081]    Extensive stage, where the cancer has spread to other regions of the body. There is a need for improved treatments of lung cancer and of inflammatory diseases of the lungs. 
         [0082]    Neurodegenerative Diseases. 
         [0083]    Diseases in the CNS pose an increasing problem in the world today, as the ageing populations suffer increasing age related health problems. In particular, the number of patients with neurodegenerative diseases is increasing. Today, 5 million Americans suffer from Alzheimer&#39;s disease; 1 million from Parkinson&#39;s; 400,000 from multiple sclerosis (MS); 30,000 from amyotrophic lateral sclerosis (ALS or Lou Gehrig&#39;s disease), and 30,000 from Huntington&#39;s disease. Because neurodegenerative diseases strike primarily in mid- to late-life, the incidence is expected to soar as the population ages. (By 2030, as many as 1 in 5 Americans will be over the age of 65.) If left unchecked 30 years from now, more than 12 million Americans will suffer from neurodegenerative diseases. Finding treatments and cures for neurodegenerative diseases is a goal of increasing urgency. 
         [0084]    Treating diseases in the CNS, not only requires good medicaments capable of imposing their effect on a disease target, they also need to be able to reach the target in the CNS, which is a great challenge due to the presence of the blood brain barrier which is impermeable to many drugs. There is therefore a great need for means and methods which increase the transport of medicaments or compositions to regions of the brain in need thereof. 
         [0085]    More than 20 serious human diseases are characterized in that abnormal accumulation of amyloid fibrils in organs may lead to amyloidosis, and this may indeed play a role in various neurodegenerative disorders. Amyloids are insoluble fibrous protein aggregates sharing specific structural traits. They arise from at least 18 inappropriately folded versions of proteins and polypeptides present naturally in the body. These misfolded structures alter their proper configuration such that they erroneously interact with one another or other cell components forming insoluble fibrils. 
         [0086]    Diseases featuring amyloid plaques: 
         [0087]    Disease Protein featured in parentheses, Alzheimer&#39;s disease (Beta amyloid, Aβ), Diabetes mellitus type 2, (IAPP (Amylin), AIAPP), Parkinson&#39;s disease (Alpha-synuclein), Transmissible spongiform encephalopathy e.g. Bovine spongiform encephalopathy (PrPSc, AprP), Fatal Familial Insomnia (PrPSc AprP), Huntington&#39;s Disease (Huntingtin), Medullary carcinoma of the thyroid (Calcitonin, Acal), Cardiac arrhythmias, Isolated atrial amyloidosis (Atrial natriuretic factor, AANF), Atherosclerosis (Apolipoprotein AI, AApoA1), Rheumatoid arthritis (Serum amyloid A, Aortic medial amyloid, Medin, Amed), Prolactinomas (Prolactin, Apro), Familial amyloid polyneuropathy (Transthyretin, ATTR), Hereditary non-neuropathic systemic amyloidosis (Lysozym Alys), Dialysis related amyloidosisCX (Beta 2 microglobulin, Aβ2M), Finnish amyloidosis (Gelsolin, Agel), Lattice conical dystrophy (Keratoepithelin, Aker), Cerebral amyloid angiopathy (Beta amyloid, Aβ), Cerebral amyloid angiopathy (Icelandic type) (Cystatin, Acys), systemic AL amyloidosis, (Immunoglobulin light chain AL, AL), Sporadic Inclusion Body Myositis (S-IBM) 
         [0088]    The International Society of Amyloidosis classifies amyloid fibrils based upon associated proteins.[17] 
         [0089]    Tau deposits, along with beta-amyloid plaques, are among the characteristic features of Alzheimer&#39;s disease. These protein deposits disrupt the communication of the nerve cells in the brain and contribute to their degeneration. Despite intensive research there is no drug available to date which can prevent this detrimental process. 
         [0090]    Delivery of Drugs Across the Blood Brain Barrier, or Export from the Brain of Unwanted Substances Such as Tau Deposits, or Beta-Amyloid: 
         [0091]    Transport of substances across the blood brain barrier (BBB) is a restricted process, in order to keep the right balance of nutrients and other substances in the brain environment. 
         [0092]    The restricted access of substances to the brain is a problem for access of certain drugs to their targets in the brain. 
         [0093]    Furthermore, harmful substances such as TAU and amyloid—beta may in some disease states have difficulty in exiting the brain, and thereby cause damage to neurons. Cannabidiol (CBD) has been shown to not only have anti-inflammatory effects, but also to aid in transport across the blood brain barrier of beta amyloid (Bachmeier et al. 2013, Molecular and Cellular Neuroscience vol. 56, p255-62). 
         [0094]    Moreover, certain processes, such as changes in the level of metabolism in a certain area of the brain may influence transport across the BBB locally. 
         [0095]    The present invention provides means for increasing local transport rates across the BBB, whereby drugs may enter the brain at a higher rate, and harmful substances may exit the brain at a higher rate than normal. 
         [0096]    Cannabidiol and Other Plant Derived Compounds Such as Terpenes for Treatment of Pain. 
         [0097]    Plant materials from the  Cannabis  family are known to comprise a large number of compounds which have been linked to have beneficial effects on different pain states, as well as on various cancers, including lung cancer and cancer in the CNS, and to a number of neurological and psychiatric conditions. Two of the most significant known chemical structures present in  Cannabis sativa  are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) ( FIG. 1 ).  FIG. 1A  shows the structure of THC, and  FIG. 1B  shows the structure of CBD. 
         [0000]    
       
                 
         
             
             
         
       
     
         [0098]    In contrary to THC, CBD is not a psychoactive molecule. However, CBD does possess a number of interesting and usefull activities on the central nervous system and on the immune system, which may be usefull therapeutically. Cannabidiol (CBD) pharmacologic effects are mediated by binding to two types of G-protein coupled receptors, cannabinoid type I and type II receptors (CB1 and CB2). CB1 is predominantly expressed in the central nervous system, and only shows very low affinty to CBD, whereas CBD has a higher affinity to the CB2 receptor which is primarily expressed in the immune system the spleen and the gastrointestinal system, but to some extent also in the brain and peripheral nervous system. 
         [0099]    There are investigations ongoing which examine the potential of CBD for treatment of neuropatic pain, Ward et al. (Br.J. Pharmacol 2014, February; 171(3); 636-645) showed that cannabidiol inhibits paclitaxel-induced neuropathic pain, without affecting the efficacy of the chemotherapy. Other variants such as CBC (Cannabichromene), CBD (Cannabidiol), CBGA (Cannabigerolic Acid), and CBN (Cannabinol) have also shown promise as analgesics. 
         [0100]    A mix of a Delta(9)-Tetrahydrocannabinol/cannabidiol (THC/CBD) mix (27 mg/mL: 25 mg/mL) was tested in patients suffering from multiple sclerosis having central neuropathic pain (CNP). The CBD/THC mixture was delivered as an oral spray. Common side effects observed included dizziness and nausea (Roq et al. Clin.Ther. 2007 sep; 29(9): 2068-2079). Other variants of THC has shown promise as analgesic compounds, including Δ8-THC (Δ8-Tetrahydrocannabinol), Δ9-THC (Δ9-Tetrahydrocannabinol) and AEA (Anandamide). 
         [0101]    Furthermore, Terpenes and terpenoids which may be derived from  cannabis  or from other plants, have shown promise for treatment of different pain states. 
         [0102]    However, there is a need for improved compositions for treatment of these diseases, as well as convenient and effective methods for their delivery to the brain, for efficient and convenient treatment. The present invention provides such improved compositions, and means for their fast delivery to the brain for improved or for ad on to existing treatment. 
         [0103]    The compositions may be used alone, of in combination with other treatments, such as systemic treatment with the compositions, or with other pain relieving medications. 
       SUMMARY OF THE INVENTION 
       [0104]    The present invention provides a device comprising cannabidiol or a variant or a derivative thereof. In some embodiments the invention provides a device comprising a flavour. In some embodiments, the device further comprises a carrier. In some embodiments, the carrier is an essential oil, or a terpene, such as a mono-, di-, or a tri-terpene. In some embodiments, the carrier is a total terpene extract from a plant, such as in non-limiting example from  cannabis . The device is designed for delivering the CBD and/or flavours to the brain via inhalation by puffing on the devicer to inhale the vapor from the device, and subsequent uptake from the oral mucosa or the lungs. Definition of puff is that the mouth is used to drag air through a passive inhaler to fill the mouth with air from the device. The air from the device is then included in the air that is breathed normally into the lungs. By including a puff in each breath (or in nearly each breath) over a prolonged period of time, the concentration of active ingredients in the lungs is built up, even in parts of the lungs which are not emptied or reached by the inhaled air. In the present invention, it is not essential that the air from the passive inhaler is taken into the lungs, as delivery to the brain preferably is by uptake through the mucosa of the oral cavity for transport to the brain. 
         [0105]    Cannabidiol, Derivatives and Variants Thereof 
         [0106]    Cannabidiol, its functional derivatives or variants, as well as the effects of any one of those on cannabinoid receptors are well described in the literature. Hanus et al. describes enantiomeric cannabidiol derivatives, their synthesis and binding to cannabinoid receptors (Hanus et al. Org Biomol Chem. 2005 Mar. 21; 3(6):1116-23). 
         [0107]    Other derivatives, variants of CBD which bind to the CD2 receptor are well known in the art, and it will be of no burden to the skilled artisan to recognize such compounds.

         [0110]    Terpenes and Terpenoids 
         [0111]    Terpenes and terpenoids constitute an interesting class of compounds with great potential in medicine (Fischedick, J. T., 2013, Doctoral thesis, Leiden University). Terpenes are naturally occurring substances that are produced by a wide variety of plants and animals and may be used in the present invention. Terpenes are any of various isomeric hydrocarbons of formula C10H16 found present in essential oils (as from conifers) and used especially as solvents and in organic synthesis; in a broader definition, terpenes are any of numerous hydrocarbons (C5H8)n found especially in essential oils, resins, and balsams. A broad range of the biological properties of terpenoids have been described, which includes cancer chemopreventive effects and anti-inflammatory activities. Terpenes are also presented as skin penetration enhancers and agents involved in the prevention and therapy of several inflammatory diseases. 
         [0112]    Terpenoids are defined as terpenes which contain additional functional groups. 
         [0113]    In example, one important terpene which may be used in the present invention is 1,8-cineole which is a natural monoterpene, and which is also known as eucalyptol. It is a major compound of many plant essential oils, mainly extracted from  Eucalyptus globulus  oil. As an isolated compound, 1,8-cineole is known for its mucolytic and spasmolytic action on the respiratory tract, with proven clinical efficacy. 1,8-cineole has also shown therapeutic benefits in inflammatory airway diseases, such as asthma and chronic obstructive pulmonary disease (COPD) (Drug Res (Stuttg). 2014 December; 64(12):638-46, Juergens U R). Further, 1,8-cineole has been shown to induce apoptosis in certain cancer cells (Murata et al. Oncol Rep. 2013 December; 30(6):2647-52). 
         [0114]    A whole set of terpenes known as  cannabis  terpenoids are terpenes which occur naturally in  cannabis , but some are also found in other plants. Such terpenes are included in the present invention, and may as such be comprised in the compositions presented herein. 
         [0115]    d-limonene is a  cannabis  terpenoid, which is known for anti cancer activities (Raphael and Cuttan, J Exp Clin Cancer Res. 2003 September; 22(3):419-24), it is a natural compound found in citrus peel oil, and in  cannabis  leaves. It further is known for its anti inflammatory activity. However, this compound is part of a large number of terpenes which are also produced by  cannabis  plants. These are termed  cannabis  terpenoids and include in non limiting embodiment compounds such as limonene, β-myrcene, α-pinene, linalool, β-caryophyllene, caryophyllene oxide, nerolidol and phytol. These compounds all have various pharmacologically relevant activities, and show synergistic effects with either THC or CBD.

In some embodiments the compositions of the invention comprise a combination of CBD and total terpene extract from  cannabis  plants. In some embodiments, the compositions of the invention comprise a combination of CBD and a terpene selected from total terpene extract from  cannabis , a mono-, di-, or tri-terpene, in combination with a carrier such as in non-limiting example a peppermint oil. 
         [0130]    Non-limiting examples of terpenes that are useful in the present invention: Anethole, has been shown to have analgesic potential in an animal model of pain. α-Bisabolol is the primary constituent (up to 50%) of the essential oil from German chamomile. It has shown anti-aging, anti-irritant, anti-inflammatory, antimicrobial, analgesic, antibiotic and anticancer activities. 
         [0131]    Borneol, has been shown to reduce nociceptive behaviour and also to posess anti-inflammatory activities (Almeida et al. The Scientific World Journal, Volume 2013, Article ID 808460, 5 pages). Borneol in addition has shown promise as a treatment for chronic pain, such as inflammatory or neuropathic pain (Jiang et al. Eur J Pharmacol. 2015 Jun. 15; 757:53-58). 
         [0132]    Camphor has been shown to inhibit heat induced pain in an animal model, in combination with 1,8-cineole, and α-pinene (Raskovic et al. European Review for Medical and Pharmacological Sciences, 2015; 19: 165-172). 
         [0133]    β-caryophyllene and caryophyllene oxide, has shown potential as oral administered drug to treat inflammatory and neuropatic pain in animal models (Klauke et al. European Neuropsychopharmacology (2014) 24, 608-620). Further, in combination with Docosahexaenoic Acid (DHA) showed improved effect on chronic pain states in animal models, with fewer side effects (Fiorenzani et al. 2014 Evidence-Based Complementary and Alternative Medicine, Volume 2014, Article ID 596312, 12 pages). 
         [0134]    1,8-cineole has been shown to inhibit heat induced pain in an animal model, in combination with camphor and α-pinene (Raskovic et al. European Review for Medical and Pharmacological Sciences, 2015; 19: 165-172), and an other study indicate an effect of 1,8-cineole on inflammatory and neuropathic pain (Quintao et al Planta Med. 2010 September; 76(13):1411-1418). 
         [0135]    Citral is a monoterpene with prophylactic and therapeutic anti-nociceptive effects in experimental models of acute and chronic pain (Nishijima et al. 2014, Eur. J. Pharmacol. Aug. 5; 736; 16-25). 
         [0136]    Citronella is a constituent of e.g. essential oil from  Melissa Officinalis  which has been shown to have promise in treatment of inflammation and pain (Bounihi et al. Advances in Pharmacological Sciences, Volume 2013 (2013), Article ID 101759, 7 pages). 
         [0137]    Delta-3-Carene, is an anti inflammatory compound which may be extracted from  Cupressus sempervirens  L. Dry leaves of this has been used for treatment of stomach pain. The essential oil from this tree has been used for treatment of headaces (Selim et al. BMC Complementary and Alternative Medicine 2014, 14:179). 
         [0138]    Farnesol which is a sesquiterpene alcohol, has been reported to have anti inflammatory activities (Ku and Lin, Food Chem. 2013 Nov. 15; 141(2):1104-13). Further, Farnesol has been tested for and found to have an antinociceptive effect in acetic acid induced writhing test, by de Oliveira Junior et al, who also found that the compound is not neurotoxic at the dosages tested (Fundam Clin Pharmacol 2013 August; 27(4):419-26). Jaggi and Singh has shown a potential for farnesyl or farnesyl derivates in treatment of neuropathic pain (Food Chem Toxicol. 2012 May; 50(5):1295-1301). 
         [0139]    Geraniol, which is the alcohol trans enantiomer of Citral, exhibit the same potential in pain alleviation as citral (Stotz et al. 2008, PLOSone3(5):E2082). 
         [0140]    Indomethacin is well known for anti inflammatory activities, as well as for effects on lung cancer or cancer in the CNS in a murine model (Castro et al. Biochem Pharmacol. 2009 Mar. 15; 77(6):1029-39 and Diament et al. Cancer Invest. 2006 March; 24(2):126-31.). Furthermore, Indomethacin is marketed as a painkiller. It is used to treat painful conditions such as arthritis, sprains and strains, back pain, period (menstrual) pain, and gout pain. 
         [0141]    Isopulegol is part of the essential of e.g. essential oil from  Melissa Officinalis  which has been shown to have promise in treatment of inflammation and pain (Bounihi et al. Advances in Pharmacological Sciences, Volume 2013 (2013), Article ID 101759, 7 pages). 
         [0142]    Linalool has shown to be very active against a number of cancer cell types (Cherng et al. Biosci Biotechnol Biochem. 2007 June; 71(6):1500-4), and further attenuates lung inflammation in an animal disease model (Wu et al. Immunopharmacol. 2014 August; 21(2):456-63). Further, linalool has been shown to attenuate allodynia in neuropatic pain, and also to be antinociceptive (Berliocchi et al. 2009; Int Rev Neurobiol 85; 221-235). 
         [0143]    Linalyl acetate, has been shown to have anti inflammatory effects (Peana et al. Phytomedicine. 2002 December; 9(8):721-6), and also significant anti cancer activities ( ). Furthermore, Linalyl acetate was shown by Sakurada et al. to be antinociceptive in an animal model of pain, the capsaicin test (Pharmacol Biochem Behav, 2011 January; 97(3); 436-443), and to inhibit neuropathic hypersensitivity induced by partial sciatic nerve ligation in mice (Kuwahata et al. 2013, Pharmacol Biochem Behav, February; 103(4):735-741). β-myrcene has shown carcinogenic effects, why it is important if using this compound to only use it by local administration, such as directly into the lung. Beta-myrcene has been shown to have anti inflammatory activities (Russo 2011), and potent antitumor effects (Sobral et al. Scientific World Journal. 2014; 2014: 953451). Additionally, β-myrcene showed potential as antinociceptive drug in mice by a low temperature hot plate method and by the acetic acid-induced writhing test (Rao et al, 1990, J Pharm Pharmacol, December; 42(12): 877-878). 
         [0144]    myrcenol, is mostly known as a fragrance of lavender, and may serve as a carrier in the present invention.

         [0146]    Nerol oxide is a well known flavour, and may be used as a carrier in the present compositions. Nerol is a major component in essential oil distillates from  Melissa officinalis  L. and experiments with such extracts suggest an effect on inflammation which may lead to pain (Bounihi et al. Adv Pharmacol Sci. 2013; 2013: 101759). 
         [0147]    Nerolidol is a naturally occurring terpene in  Cannabis  as well as ginger, jasmine, lavender and tea tree. It has been shown to cause cell cycle arrest and induce apoptosis in hepatucellular cancer cells (Ferreira et al. Toxicology in Vitro, Volume 26, Issue 2, March 2012, Pages 189-196). The compound may also have antiinflammatory effects, and effects on pain, as demonstrated by topical application for skin conditions 
         [0148]    Oridonin has been shown to inhibit a number of different cancer cell lines, including nonsmall cell lung cancer cells (Ikezoe et al. International Journal of Oncology, Oct. 1, 2003, Pages: 1187-1193), and also have significant effects on inflammatory conditions (Gui et al. BMC Complementary and Alternative Medicine (2015) 15:117). 
         [0149]    α-pinene has been shown to inhibit heat induced pain in an animal model, in combination with 1,8-cineole, and camphor (Raskovic et al. European Review for Medical and Pharmacological Sciences, 2015; 19: 165-172). 
         [0150]    Peppermint oil is also reported to be anti-inflammatory, and has indeed been used in capsule form for treatment of asthma. It may further be used as a carrier in the present invention. 
         [0151]    Phenyl acetic acid and its derivatives, such as Diclofenac, Nepafenac and Bromfenac are well known for their ability to reduce pain and inflammation. Phytol, reduces inflammation (Silva et al., Fundam Clin Pharmacol. 2014 August; 28(4):455-64. Phytol, a diterpene alcohol, inhibits the inflammatory response by reducing cytokine production and oxidative stress.). Furthermore, phytol has shown promise as a cytotoxic agent to cancer cells (Pejin et al. Nat Prod Res. 2014; 28(22):2053-6). 
         [0152]    Terpineol, in vitro experiments indicate that gamma terpineol inhibits cancer cell proliferation and induces apoptosis (Wu et al. Int J Clin Exp Pathol. 2014; 7(10): 6524-6533). Further, terpineol has shown promising effects in models of lung inflammatory disease such as COPD (Tsou et al. Evidence-Based Complementary and Alternative Medicine, Volume 2014, Article ID 465025). 
         [0153]    Terpinen-4-ol, has been shown to have anti inflammatory activities (Ninomiya et al. Biol. Pharm. Bull. 36(5) 838-844 (2013)), and induces apoptosis in human nonsmall cell lung cancer in vivo (Wu et al. Evidence-Based Complementary and Alternative Medicine, page 1-13 
         [0154]    Thymol, attnuates allergic airway inflammation in a mouse asthma model (Zhou et al. Fitoterapia. 2014 July; 96:131-7). Thymol protect against radiation induced DNA damage, why thymol is not in the compositions for use in combination with radiation therapy Archana et al Integr Cancer Ther. 2011 December; 10(4):374-83. 
         [0155]    Thymoquinone has been shown to have effects on nonsmall cell lung cancer cells when combined with benzo(a)pyrene (APJCP vol 14, issue 10, 2013, Ulasli et al.). Additionally, thymoquinone has been shown to be anti inflammatory (Khader and Eckl, Iran J Basic Med Sci 2014; 17:950-957).

         [0173]    In one embodiment, the invention is a passive inhalator or other device useful for delivering compositions in the oral cavity or nose or to the lungs as a gas, or a vapor or a mist or an aerosol without heating, wherein the device or passive inhalator comprises the compositions of the invention. A passive inhalator is a device which allows for the compositions of the invention to be delivered without excessive heating, such as without heating above a temperature above any one of 140° C., such as above 150° C., such as above 160° C., such as above 170° C. or above 180° C., such as without heating above any one of 60° C., 70° C., 80° C., or 90° C. without heating at all. One example of such a device is described below. 
         [0174]    In some embodiments, a passive inhaler is an inhaler without any heating. In some embodiments, a passive inhaler is an inhaler without heating the ingredients above any one of 60, 70, 80, or 90° C. In some embodiments, a passive inhaler is an inhaler without heating the ingredients above any one of 140° C., such as above 150° C., such as above 160° C., such as above 170° C. or such as without heating the ingredients above 180° C. 
         [0175]    Examples of Devices for Delivery of the Compositions as a Vapor: 
         [0176]    It has not previously been shown that CBD compositions may be delivered to the lungs as a vapor or a gas using a passive inhalator device. In one preferred embodiment, the compositions, methods and uses of the present invention are for use with a passive inhalator device. Such devices may have various designs, and in non limiting example they may be such as those or similar to those disclosed in WO2011107104 (hereby included by reference) or those disclosed in PCT/DK2013/000051. 
         [0177]    An improved device may also be used in the present invention, which in principle is similar to the device disclosed in WO2011107104, but to which means are introduced to increase the availability of the carrier, and to avoid escape of the carrier from the device if the user sucks from the wrong end of the device. 
         [0178]    In one embodiment, a hard porous plastic (or similar) filter is placed between the ball and the pin shaped release device. This filter will prevent escape of the carrier or other substance from the device, and will be able to absorb the carrier, and thereby, due to the increased exposure area, provide increased efficiency of the delivery of substances from the device. The pore size may be varied to increase the resistance, or to increase or decrease the evaporation of the absorbed substance. Further, the hardness of the filter may be adjusted in order to avoid penetration by the release device, or built into the release device, or the release device is a hard filter. 
         [0179]    The filter may in some embodiments be of a hardness which allow the inhaler to be activated. 
         [0180]    In some embodiments the filter may be between 1 mm and 40 mm long. In some embodiments, the filter may have a pore size of between 0.01 micrometer and 10 micrometer. The filters or device may be produced with groves to regulate airflow and flowdrop. 
         [0181]    In one embodiment, the device may comprise a porous or acetate filter in the inhalation part, in order to prevent materials to escape from the inhalation device. This porous filter may be integrated in the central air passage of the existing barrier, e.g. star shaped barrier in the inhalation part. The porous filter may be separate from the barrier. 
         [0182]    The filter may be between 1 mm and 20 mm long. 
         [0183]    In some embodiments, it is preferred that there also is an increased area at which the carrier may pick up the active pharmaceutical ingredient (API) (in this case CBD). This may be achieved by making the ball in the inhalation part smaller than the ball in the middle. In this way, the device may be designed to allow passage of the API past the ball, and to be absorbed by the filter. When the carrier passes through the first compartment and the filter, it will take up the API with increased efficiency. This filter may in one non limiting embodiment consist of a normal acetate filter. 
         [0184]    This improved device allows for improved efficacy of delivery, by higher concentration of API and carrier in the inhaled air from the device, as well as avoidance of escape of fluids and materials from the device. 
         [0185]    It is important that the material of which the filters are made will not absorb the substances comprised in the device, such as the carriers and the API. It is also important that the filters have a pore size that allows air to be readily puffed through the filter by the user. Also, the filter material must be of a kind that will not release unwanted compounds from the filter material during use. 
         [0186]    In non-limiting example, the filters may be made of polypropylene (PP) or polyurethane (PUR), or the like. 
         [0187]    In one embodiment, a porous filter may also be placed between the balls, to create distance between the balls during production process and activation process and for the purpose of separating the API and the carriers after activation. 
         [0188]    In some embodiments, (See  FIG. 2 . Detail C: C-100) a heating VAVE device CAP may be attached to the device which is activated when air is sucked into the device, and which will heat the air which is sucked into the device to a temperature not exceeding any one of 60, 70, 80, or 90° C., and in a further embodiment, without heating above a temperature above any one of 140° C., such as above 150° C., such as above 160° C., such as above 170° C. or above 180° C. In other embodiments, no heating device is attached or connected to the passive inhaler device used for delivery of the compositions of the present invention. 
         [0189]    In some embodiments, the vapor or gas or mist or aerosol created from the compositions of the present invention are delivered by positive airway pressure. In some embodiments, the present invention is a passive inhaler device comprising the compositions of the present invention. 
         [0190]    Dosages 
         [0191]    Relationship between components of the present invention—CBD/THC/terpenes vs carriers. In some embodiments, the passive inhaler device comprises active compounds such as CBD, THC, tobacco extracts and/or terpenes in a 1:1 relationship with a carrier, such as peppermint oil. In some embodiments, the relationship between the active compound and the carrier may be within the range of between 5:1 and 1:5, such as between 4:1 and 1:4, such as between 3:1 and 1:3, such as between 2:1 and 1:2, such as about 1:1. 
         [0192]    Dosages in the Passive Inhaler Device. 
         [0193]    The actual dosage received in the body is what matters. Depending on which device is used, the actual amount of active compound and carrier present in the device may vary, and given the knowledge from the present invention, that these compounds may be delivered to the lungs in pharmaceutically relevant dosages without excessive heating, is without any undue burden to adjust the dosage in a given device to achieve a desired delivery of active compound into the lungs. 
         [0194]    In some embodiments, the compositions of the invention are made to deliver between 0.1 mg to 15 mg active compound to the lungs or to the mucosa of the oral cavity (for transport to the brain) over a period of 1-6 hours. In some embodiments, the composition of the invention are made for delivery of 0.1 mg to 15 mg CBD and/or THC into the lungs or mucosa of the oral cavity over a period of 1-6 hours. 
         [0195]    In some embodiments, a dosage of between 0,1 and 50 mg of one or more terpenes are delivered into the lungs or to the mucosa of the oral cavity over a period of 1 to 6 hours. In some embodiments, patients are administered the compositions of the invention 2 times per day for 1 to 6 hours. 
         [0196]    In some embodiments, the compositions of the invention are administered to a patient for periods of one week at a time interrupted by a pausing during which a doctor may inspect the status of disease. 
         [0197]    In some embodiments, the invention is a passive inhaler device comprising CBD and a carrier, wherein the CBD is between 1 and 80% pure (by weight). Such as between 1 and 75%, such as between 10 and 75%, such as between 20 and 75%, such as between 25 and 70% pure. 
         [0198]    In some embodiments, the passive inhaler device of the invention comprises a total of between 1 and 75% by weight CBD, such as between 10 and 70% CBD, such as between 10 and 60% CBD, such as between 10 and 50% CBD, such as between 15 and 40% CBD. 
         [0199]    Method of Treatment 
         [0200]    The present invention provides a method of treatment, wherein the passive inhaler comprising the compositions of the invention is used for delivering gaseous or vapor or mist forms of the composition to the mucosa of the oral cavity or to the lungs to facilitate delivery of the composition to the CNS and thereby treat neurodegenerative diseases, such as any one of plaque related disorders of the CNS, such as parkinsons disease, alzheimers disease, schizophrenia, transmissible spongiform encephalopathy, bovine spongiform encephalopathy, huntingtons disease, Familial amyloid polyneuropathy, Finnish amyloidosis, Lattice conical dystrophy, cerebral amyloid angiopathy, cerebral amyloid angiopathy Icelandic type. 
         [0201]    The present invention also provides a method of treatment, wherein the passive inhaler comprising the compositions of the invention is used for delivering gaseous or vapor or mist forms of the composition to the mucosa of the oral cavity or to the lungs to facilitate delivery of the composition to the CNS and thereby treat diseases selected from the list of psychosis, anxiety, depression, emitic conditions such as any one of motion sickness, side effects of opioid analgesics, side effects of general anaesthetics, side effects of chemotherapeutics, morning sickness, severe cases of gastroenteritis. 
         [0202]    The present invention also provides a method of treatment, wherein the passive inhaler comprising the compositions of the invention is used for delivering gaseous or vapor or mist forms of the composition to the mucosa of the oral cavity or to the lungs to facilitate delievry of the composition to the CNS and thereby treat diseases selected from the list of tumours in the central nervous system (CNS), such as any one of glioblastoma, metastases of tumors originating from other parts of the body, such as from Lung cancer, breast cancer, genitourinary tract cancers, osteosarcoma, melanoma, head and neck cancer, neuroblastoma, gastrointestinal cancers, colorectal carcinoma, pancreatic carcinoma and lymphoma. In some embodiments, the method of treatment for cancer in the CNS is for use in combination with radiation therapy, or in combination with chemotherapy or both. 
         [0203]    In some instances, the methods of treatment of the present invention is for treatment of patients which do not respond to treatment with for example CBD or a combination of CBD and THC when administered orally, systemically or by smoking. 
         [0204]    In some embodiments, the methods of treatment of the present invention are methods for enhancing transport of substances across the blood brain barrier. 
         [0205]    In some embodiments, the passive inhaler device of the invention comprises flavours or compounds which increase permeability of the blood brain barrier, and thereby allows for increased transport or diffusion of substances, such as of medicaments which do not normally cross the blood brain barrier in sufficient amount in order to have an optimal effect on a brain target. Such compounds may be in non limiting example any one or more of a mono-, di- or a tri-terpene, a terpene, a tobacco flavour, or a compound known for increasing metabolism such as coffeine or nicotine. By delivering the compounds with the device via the oral mucosa, the effect on the permeability of the blood brain barrier will remain local, and will not cause a general change in permeability of the whole blood brain barrier. 
         [0206]    The present invention thus provides a method of increasing permeability of the blood brain barrier to make compounds present in the blood circulation able to cross the blood brain barrier and enter the cerebrospinal fluid and be transported to its brain target. In other embodiments, the present invention provides a method of increasing permeability of the blood brain barrier to allow compounds, such as amyloid or tau proteins to exit the brain and be transported away by the blood circulation system.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0228]    The compositions of the present invention, for delivery via the nasal passage to the brain, may be delivered by various means known in the art, to provide the composition in a form which will be absorbed through the membranes in the back of the nose or the oral mucosa. In some embodiments, the passive inhaler device of the invention is anyone of the devices described below, or in WO2011/107104, or similar to those. 
         [0229]    In one embodiment, such delivery may be by use of a device similar to that disclosed in WO2011/107104 (WO2011/107104 included by reference), in which 3 balls separate carrier from the active pharmaceutical ingredient (API). The present invention further provides a device which is improved in comparison to the device disclosed in WO2011107104. This improved device provides means to increase availability of the carrier, and to avoid carrier escaping the device if the user suck from the wrong end of the device, as well as means to avoid escape of material such as API or tobacco and/or marihuanna leaves etc. from the device in the end at which the user puffs from. 
         [0230]    In one embodiment, a hard porous plastic (or similar) filter (A-100) is placed between the ball and the pin shaped release device. This filter will prevent escape of the carrier or other substance from the device, and will be able to absorb the carrier, and thereby, due to the increased exposure area, provide increased evaporation of the carrier. The increased evaporation of carrier will allow an increased efficiency of the delivery of substances from the device. The pore size may be varied to increase the resistance, or to increase or decrease the evaporation of the absorbed substance. Further, the hardness of the filter may be adjusted in order to avoid penetration by the release device. In one embodiment, the filter is attached to the release device, or is built into the release device, or the release device is a hard filter. 
         [0231]    The filter (A-100) may in some embodiments be of a hardness which allow the inhaler to be activated. 
         [0232]    In some embodiments, the filter (A-100) may be between 1 mm and 40 mm long. 
         [0233]    In some embodiments, the filter (A-100) may have a pore size of between 0.01 micrometer and 10 micrometer. Produced with groves to regulate airflow and flowdrop. 
         [0234]    In one embodiment, the device may comprise a porous or acetate filter (D) in the inhalation part, in order to prevent materials to escape from the inhalation device. This porous filter may be integrated in the central air passage of the existing barrier, e.g. star shaped barrier in the inhalation part. The porous filter (D) may be separate from the barrier. 
         [0235]    The filter (D) may be between 1 mm and 20 mm long. 
         [0236]    In some embodiments, it is preferred that there also is an increased area at which the carrier may pick up the API. This may be achieved by making the ball in the inhalation part smaller than the ball in the middle. In this way, the device may be designed to allow passage of the API past the ball, and to be absorbed by the filter (D-100). When the carrier passes through the first compartment and the filter (D-100), it will take up the API with increased efficiency. This filter (D-100) may in one non limiting embodiment consist of a normal acetate filter. 
         [0237]    This improved device allows for improved efficacy of delivery, by higher concentration of API and carrier in the inhaled air from the device, as well as avoidance of escape of fluids and materials from the device. 
         [0238]    It is important that the material of which the filters are made will not absorb the substances comprised in the device, such as the carriers and the API. It is also important that the filters have a pore size that allows air to be readily puffed through the filter by the user. Also, the filter material must be of a kind that will not release unwanted compounds from the filter material during use. 
         [0239]    In non-limiting example the filter (A-100) and/or filter (D-100) may be made of polypropylene (PP) or polyurethane (PUR), or the like. 
         [0240]    In one embodiment, a porous filter may also be placed between the balls, to create distance between the balls during production process and activation process and for the purpose separating the API and the carriers after activation. 
         [0241]    The improvements in the device may also be described as follows: 
         [0242]    (A-100): Hard PUR/PP etc. Stopfilter (A-100) Dose controle, Airflow and flowdrop improvement: 
         [0243]    The hard PUR filter, (A-100), between the last inserted ball and the pin/plounger(F-100), enlarges the surface of the carriers and absorbing the carriers while moving the plounger(F-100) into the device for activation. Its function is also to stop liquids floating from the device and to keep the separation of the substances after activation. The function of this filter is also to bring possibility for the consumer to puff from both points of the device, without sucking the liquid extracts/substances into the mouth, as if this was a straw. 
         [0244]    The function of this filter is also to push the 3 sealing bodies and the substances between these bodies into the first compartment, without collapsing, in a way, to stay partly in the second compartment partly in the first compartment or between these two compartments, after the activation process. This is to assure the use of the expanded area that the substances are vaporizing from and to controle the liquids in the device to stay away from the plounger point (F-100), opposite the mouthpiece point (E-10) and (E-100). 
         [0245]    DETAIL: (B) &amp; (C) CAP improvement, dose controle: 
         [0246]    A solution with the cap( 27 ). DETAIL B, added to open for solutions (C-10) that can bring different dosing controlling abilities to this improved device, such as electronic counters, electronic blinking lights, that can be in green turning to red, after a number of puffs of the right pressure, delivering the fixed needed dose per puff, depending on the nature of API that this device delivers. 
         [0247]    Cap ( 27 ), that can have the feature incorporated Heat-flaps:on/off &amp;battery (C-100), connected with the technology in the mouthpiece and incorporated technology with light(s) or whistle(s) to bring signals to the consumer when to stop further intake, after receiving full dose. 
         [0248]    Accessories can make devices look in the way, that consumers need, to “take the medicine” The cap solution is a way to improve the device in a way, that brings the consumer into a more acceptable lifestyle, while consuming the needed treatment. 
         [0249]    The cap solution improves the feasibility of activating the device more easy. It also shows from where to puff, having the mouthpiece in the one point. 
         [0250]    The cap can be designed in different designs and colors and materials, as long as it is designed to hold the inhaler inside, in a way to provide air passing through, when inserted and activated. 
         [0251]    (D-100) Soft acetate etc. improvement: 
         [0252]    The soft filter, (D-100), to be inserted in the position in the inhalation part of the device. This filter avoids particles to pass through the star hole and absorbes the API to enlarge the surface for volatile “delivering” the liquid API as a gas, with or without being picked up by volatile carriers, that is fysically moved by air containing water vapor, nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, xenon and different particles from the area, that can be particles from environmental character or pollution, like in cities we find high consentration of diesel combustion, charcoal combustion, smoking particles, combustion particles from chimneys etc. airborne latex allergens, allergenic proteins etc. and these particles can be from nature like hay fever from grass, pollinosis from pollens of any plant, animal dander etc. 
         [0253]    This filter can be produced from supplyer directly in connection with different fermented and cutted tobacco or marihuana etc. leaves together with the starhole filter.

         [0261]    Effects of the treatments presented in the invention relating to lung inflammation, may be in non limiting example measured as improvements of various disease markers. In non-limiting example, such markers may include any one of an inflammation marker selected from the list of C-reactive protein (CRP), soluble tumour necfosis factor-receptor (TNFR-1), osteoprotegrin (OPG) and monocyte chemoattractant protein-4 (MCP4) (Eagan et al. 2010 European Respiratory Journal vol 35 no 3 p 540-548). Other objective indications of improvement, such as improvement in a disease symptom may also be taken as measurement for effect. One effect by which effect may be measured is general well being, mucus coughing coloured with e.g. tar particles. Improvement in ease of breathing. 
         [0262]    Effects of the treatments presented in the invention relating to lung cancer or cancer in the CNS, may in non limiting example be measured as improvements of various disease markers. In non limiting example, this may be proliferation arrest, prevention of spreading of disease into other tissues, shrinking of tumor mass. 
         [0263]    Effects of the treatments presented in the invention relating to epilepsy, may in non limiting example be measured by reduction in severity of attacks or fewer attacks. 
         [0264]    Effects of the treatments presented in the invention relating to the use of the passive inhaler as an anti-emetic, may in non limiting example be measured by reduction in vomiting, or in the sensation of nauseaness. 
         [0265]    Effects of the treatments presented in the invention relating to the use of the passive inhaler to treat anxiety, depression or psychosis, may be measured by a reduction in the symptoms of those diseases.

       EXAMPLES 
     Example 1 
       [0267]    The compositions and methods of the invention will be tested in relevant animal models of inflammatory lung diseases, including models of acute lung injury and COPD. 
         [0268]    Various dosages of CBD will be delivered to the lungs by use of passive inhaler devices comprising different dosages of CBD and a carrier to identify the optimal dosage range. 
       Example 2 
       [0269]    In some applications, nicotine may be used in the inhaler. Nicotine may be delivered in three forms with tobacco flavours: 
         [0270]    A: As dried fermented tobacco leaves in cut form (this form will provide a stimulus to the brain similar to that of natural tobacco flavours as seen when smoking) 
         [0271]    B: As heat (247 degree Celcius) or high pressure destilled extract made by a 7 phase distillation process, wherein the extract comprises nicotine and possibly some tobacco flavours. 
         [0272]    C: As a blended mass of tobacco leaves, extracted by nut oil, tasteless oil or propylene glycol. In some instances it may be washed with CO2 or ethanol in the aromaextration process. The composition is mixed with the composition of B), and leaf parts are removed by pouring through a cloth or the like. The resulting fluid will be uniform and volatile and able to release its natural tobacco flavours 
       Example 3 
       [0273]    CBD extraction from  Cannabis  plants is done similar to nicotine extraction from tobacco as described in example 2. 
         [0274]    CBD is extracted at 250 degrees Celcius. 
         [0275]    Cannabidiol (CBD) has a boiling point of: 160-180 degrees C./320-356 degrees Fahrenheit 
         [0276]    CBD may also be extracted by other methods, such as CO2 extraction, Ethanol or olive oil extraction:
       CO2 extraction. The supercritical (or subcritical) CO2 method uses carbon dioxide under high pressure and extremely low temperatures to isolate, preserve, and maintain the purity of the medicinal oil. This process requires expensive equipment and a steep operational learning curve. But, when done well the end product is safe, potent, and free of chlorophyll.   Ethanol. High grade grain alcohol can be used to create high quality  cannabis  oil appropriate for vape pen cartridges (E-cigarettes using heating) and many other products. But this extraction method destroys the plant waxes, which may have health benefits that are favored by some product-makers.   Olive oil. Extra virgin or otherwise, olive oil can also be used to extract  cannabis  oil. Dr. Arno Hazekamp, director of phytochemical research at Bedrocan BV, which supplies medical  cannabis  for the Dutch Health Ministry, reports this method is both safe and inexpensive, “You won&#39;t blow yourself up making  cannabis -infused olive oil.”  Cannabis -infused olive oil—whether CBD-rich or THC-dominant—is however perishable and should be stored in a cool, dark place.

         [0295]    Properties: Analgesic, Euphoriant 
       Example 4 
       [0296]    In some instances, it will be advantageous to supplement treatment of the present invention with systemic treatment with CBD. For this purpose CBD in capsule form up to a maximum of 100-200 mg daily, preferably 100 mg daily, may be administered. 
         [0297]    CBD in capsule form, may be delivered via the gastrointestinal tract. 
       Example 5 
       [0298]    10 COPD patients were given a device comprising 8.6 mg CBD and peppermint oil to a total of about 75 mg. 
         [0299]    The patients took 200 puffs in about 4-6 hours, wherein the patients took one puff through the device and included the air from that one puff in each breath of air that was taken into the lungs. This procedure was continued for 4-6 hours. 
         [0300]    Result: the patients felt an improved well being, they coughed up black mucus, and felt an improved ease of breathing. 
       Example 6 
       [0301]    10 COPD patients will be given a device comprising 8.6 mg CBD and a 50:50 mixture of peppermint oil and total  cannabis sativa  terpene extract to a total of about 75 mg. 
         [0302]    The patients will take 200 puffs in about 4-6 hours, wherein the patients took one puff through the device and included the air from that one puff in each breath of air that was taken into the lungs. This procedure was continued for 4-6 hours. 
         [0303]    Some patients will be given two times 200 puffs per day, and some will be given only 200 puffs per day. 
         [0304]    Some patients will as a control be given the CBD/peppermint oil device of example 5. 
       Example 7 
       [0305]    A patient suffering from multiple sclerosis experiencing continuous pain, which he normally only can treat by smoking of  cannabis , which has the side effect of making him constantly under influence by the drug, and thereby being mentally sedated in addition to the effect on the pain. The patient does not respond to CBD gel capsules when taken orally, and is thus a non-responder to oral CBD. 
         [0306]    The patient tested the passive inhaler devices of the invention loaded with three different compositions:
       1) Negative control only loaded with peppermint oil as a carrier.   2) Positive loaded with CBD and peppermint oil, wherein the concentration of the CBD initially was 61%, and after mixing with carrier (peppermint oil), the final concentration of CBD was 30% by weight.   3) Positive loaded with CBD (31%) and carrier (peppermint oil), the final concentration of CBD was 15% by weight.       
 
         [0310]    The patient experienced severe pain in the legs and feet, and the sensation of pain was not influenced by inhaling the negative control after about 15 minutes of puffing on device number 1. The patient however responded to both inhaler number 2 and 3. His response to inhaler number 3 was partial, as he after puffing on device number 3 for about 12 minutes, he still experienced moderate pain, but described the effect as good. Device number 2 with 30% CBD by weight had the best effect, it removed so much pain that the patient did no longer have to use energy to control his pain. This effect appeared after about 10 minutes, and lasted for about 16 minutes after which he had to puff again. This allowed him to walk about in the room without feeling pain. 
         [0311]    The patient had not smoked  cannabis  for 3 days before the testing of the devices. He explained that it was a relief not to feel influenced by the  cannabis , as the devices number 2 and 3 gave the pain relief without affecting him otherwise (no psychoactive effects).
