title: Effects of cannabis
text: at Johns Hopkins University School of Medicine showed that very heavy use of marijuana is associated with decrements in neurocognitive performance even after 28 days of abstinence. The feeling of increased appetite following the use of cannabis has been documented for hundreds of years, and is known colloquially as "the munchies" in the English-speaking world. Clinical studies and survey data have found that cannabis increases food enjoyment and interest in food. A 2015 study suggests that cannabis triggers uncharacteristic behaviour in POMC neurons, which are usually associated with decreasing hunger. Rarely, chronic users experience a severe vomiting disorder, cannabinoid hyperemesis

text: days per month, about one-third might experience symptoms. Cannabinoid hyperemesis syndrome has been reported more frequently in people that use cannabis daily (47.9% of patients) and greater than daily (23.7% of patients), compared to once weekly users (19.4% of patients) and less frequent users (2.4% of patients). A significant increase in the incidence of cannabinoid hyperemesis syndrome (and other marijuana-related visits to the emergency department) has been noted in U.S. states that have legalized marijuana, with the incidence of cyclic vomiting prominently doubling in the US state of Colorado after legalization. As the use of marijuana continues to be legalized

A French review from 2009 came to a conclusion that cannabis use, particularly that before age 15, was a factor in the development of schizophrenic disorders. A 2008 National Institutes of Health study of 19 chronic heavy marijuana users with cardiac and cerebral abnormalities (averaging 28 g to 272 g (1 to 9+ oz) weekly) and 24 controls found elevated levels of apolipoprotein C-III (apoC-III) in the chronic smokers. An increase in apoC-III levels induces the development of hypertriglyceridemia. The genus "Cannabis" contains two species which produce useful amounts of psychoactive cannabinoids: "Cannabis indica" and

Aside from a subjective change in perception and mood, the most common short-term physical and neurological effects include increased heart rate, increased appetite and consumption of food, lowered blood pressure, impairment of short-term and working memory, psychomotor coordination, and concentration. Some users may experience an episode of acute psychosis, which usually abates after six hours, but in rare instances, heavy users may find the symptoms continuing for many days. A reduced quality of life is associated with heavy cannabis use, although the relationship is inconsistent and weaker than for

Many people are struck by the notion that cannabis could induce symptoms of nausea and vomiting, given the common perception that cannabis can be used to prevent nausea and vomiting. It is unclear why cannabinoid hyperemesis syndrome is disproportionately uncommon in recognition of how widely used cannabis is throughout the world. There may be genetic differences between cannabis users that affect one's risk for developing cannabinoid hyperemesis syndrome. The pathophysiology of the syndrome is also unclear, especially

text: The drug use must be "implicated" in the emergency department visit, but does not need to be the direct cause of the visit. Most of the illicit drug emergency room visits involved multiple drugs. In 129,000 cases, cannabis was the only implicated drug. Effects of chronic use may include bronchitis, a cannabis dependence syndrome, and subtle impairments of attention and memory. These deficits persist while chronically intoxicated. Compared to non-smokers, people who smoked cannabis regularly in adolescence exhibit reduced connectivity in specific brain regions associated with memory, learning, alertness, and executive function. One study suggested that sustained heavy, daily, adolescent

This phenomenon has been touched on in popular culture: notorious instances appear in the films "Monty Python's The Meaning of Life" (1983) and "Stand By Me" (1986). Intense vomiting in ayahuasca ceremonies is a common phenomenon. However, people who experience "la purga" after drinking ayahuasca, in general, regard the practice as both a physical and spiritual cleanse and often come to welcome it. It has been suggested that the consistent emetic effects of ayahuasca—in addition to its many other therapeutic properties—was of medicinal benefit to indigenous peoples of the Amazon, in helping to clear

When sold under the trade name Sativex as a mouth spray, the prescribed daily dose in Sweden delivers a maximum of 32.4 mg of THC and 30 mg of CBD; mild to moderate dizziness is common during the first few weeks. Relative to inhaled consumption, peak concentration of oral THC is delayed, and it may be difficult to determine optimal dosage because of variability in patient absorption. In 1964, Albert Lockhart and Manley West began studying the health effects of traditional cannabis use in Jamaican communities. They developed, and in 1987 gained

There has been a limited amount of studies that have looked at the effects of smoking cannabis on the respiratory system. Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, coughing, and other symptoms of chronic bronchitis. Regular cannabis use has not been shown to cause significant abnormalities in lung function. Cannabis smoke contains thousands of organic and inorganic chemical compounds. This

The hyperemetic phase is characterized by the full syndromal symptoms of cannabinoid hyperemesis syndrome, including persistent nausea, vomiting, abdominal pain, and retching. Retching can occur up to 5 times per hour. It is very difficult to take food or medicine by mouth during this stage, and patients may develop a fear of eating. Weight loss and dehydration due to decreased oral intake and vomiting are possible. Compensatory exposure to hot water, even for hours at a

text: Cannabinoid hyperemesis syndrome Cannabinoid hyperemesis syndrome can occur with cannabis use and is characterized by recurrent nausea, vomiting, and crampy abdominal pain. These symptoms have been reported to be improved temporarily by taking a hot shower or bath, or more fully by stopping the use of cannabis. It is important that cannabinoid hyperemesis syndrome be distinguished from other causes of nausea and vomiting, such as cyclic vomiting syndrome. The pathogenesis of cannabinoid hyperemesis syndrome is unclear, but it may involve accumulation of exogenous cannabinoids or alterations in the brain's regulation of body temperature. While definitive treatment involves abstinence from cannabinoids,

Cannabinoid hyperemesis was first reported in the Adelaide Hills of South Australia in 2004. Cannabinoid hyperemesis syndrome is not very well known, and some healthcare providers may view it as a "rare, kind of funny disease." Some emergency room physicians have referred to the symptoms as "scromiting," a portmanteau of "screaming" and "vomiting." In lieu of a correct diagnosis, the average patient in the US may owe $100,000 USD or more in medical bills through emergency department visits. An emergency department physician in

When marijuana is being used as an adolescent, the chances of getting addicted increase almost instantly. This is because adolescents who smoke marijuana are twice as likely as adults to become addicted. Young people believe that marijuana is a safe drug and it cannot be harmful because it is "natural," however this is untrue. Marijuana can cause changes in the brain that impair learning, this especially effects adolescents as their brains have not finished developing. The drug impacts their brains heavily because it reduces thinking, memory,

These widespread legends claim that it is easy to overdose on the smokeable variant of cannabis and that it is extremely dangerous and addictive when compared to alcohol and tobacco. Withdrawal from heavy, chronic cannabis use does not usually exceed 3–4 days, but it has the potential to be psychologically addictive. Withdrawal symptoms are generally mild - loss of appetite, insomnia, feelings of uneasiness/anxiety, tension, stomach ache, headache and irritability all being common symptoms. There are studies that show no actual increased risk of cancer from smoking marijuana, even when duration of use is

title: Correlation does not imply causation
text: children like watching more TV than less violent ones. A correlation between recreational drug use and psychiatric disorders might be either way around: perhaps the drugs cause the disorders, or perhaps people use drugs to self medicate for preexisting conditions. Gateway drug theory may argue that marijuana usage leads to usage of harder drugs, but hard drug usage may lead to marijuana usage (see also "confusion of the inverse"). Indeed, in the social sciences where controlled experiments often cannot be used to discern the direction of causation, this fallacy can fuel long-standing scientific arguments. One such example can be found

Acute effects may include anxiety and panic, impaired attention, and memory (while intoxicated), an increased risk of psychotic symptoms, and possibly increased risk of accidents if a person drives a motor vehicle while intoxicated. Psychotic episodes are well-documented and typically resolve within minutes or hours. There have been few reports of symptoms lasting longer. According to the United States Department of Health and Human Services, there were 455,000 emergency room visits associated with cannabis use in 2011. These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use.

The rate goes up to one in six among those who begin use as adolescents, and one-quarter to one-half of those who use it daily according to a NIDA review. A 2013 review estimates daily use is associated with a 10-20% rate of dependence. The highest risk of cannabis dependence is found in those with a history of poor academic achievement, deviant behavior in childhood and adolescence, rebelliousness, poor parental relationships, or a parental history of

text: People who are cannabis dependent have the inability to stop or decrease using cannabis on their own. Marijuana addiction is more common among heavy users. Marijuana use can lead to increased tolerance and, in some users, withdrawal symptoms when trying to stop. Cannabis withdrawal symptoms can occur in one half of patients in treatment for cannabis use disorders. These symptoms include dysphoria (anxiety, irritability, depression, restlessness), disturbed sleep, gastrointestinal symptoms, and decreased appetite. Most symptoms begin during the first week of abstinence and resolve after a few weeks. The withdrawal symptoms are usually not severe, even after heavy use. Cannabis
