text: drug, but psychiatrist Dr Bill MacEwan believes that drug dealers in British Columbia are intentionally lacing cannabis with methamphetamine to make it more addictive. He had some psychiatric patients that claimed they only smoked pot but their drug tests were positive for methamphetamine use. The most common adulterants found in 1998 in samples in Rome, Italy were lidocaine and caffeine. Cocaine is sometimes mixed with methylamphetamine, methylphenidate, and ephedrine, but is usually mixed with non psychoactive chemicals such as mannitol, inositol, pectin, glucose, lactose, saccharin, white rice flour, and maltodextrin. Other local anesthetics such as procaine are very commonly used.

The emergence of fentanyl-laced cocaine has led to an increase in cocaine overdose fatalities in New York City. Though marijuana is less likely to be adulterated than hard drugs are, it still occurs, and has been reported in several countries. In the Netherlands two chemical analogs of Sildenafil (Viagra) were found in adulterated marijuana. In 2008, 30 German teenagers were hospitalized after the marijuana which they smoked was found to have been contaminated with lead (presumably metallic lead particles), which was added in order to

The short term effects of cannabis can be altered if it has been laced with opioid drugs such as heroin or fentanyl. The added drugs are meant to enhance the psychoactive properties, add to its weight, and increase profitability, despite the increased danger of overdose. Heavy, long-term exposure to marijuana may have biologically based physical, mental, behavioral and social health consequences and may be "associated with diseases of the liver (particularly with co-existing hepatitis C), lungs, heart, and vasculature".

Drug researchers learned that some dealers were spiking marijuana when they tested US teens who stated that they had only used a single illegal drug (marijuana) and the teens tested positive for marijuana and PCP. Some dealers who have a very small quantity of MDMA powder to sell "spike" it with less expensive and easier to produce methamphetamine powder.

Because the metabolites may persist in the blood for many days, the test may detect marijuana that was used many days earlier long after the effects have worn off". As a result, President Ronald Reagan instituted a "Zero Tolerance" drug policy across all of the U.S. armed services, which started

This is largely because it contains high levels of the chemicals 6-acetyl-2,3,4,5-tetrahydropyridine and 2-acetyl-1-pyrroline, very powerful aroma compounds that are used by food and other industries to make products that either smell like popcorn, bread, or other foods containing the compound in nature, or for other purposes. Popcorn as a breakfast cereal was consumed by Americans in the 1800s and generally consisted of popcorn with milk and a sweetener. Popcorn balls (popped kernels stuck together with

Marijuana is commonly smoked in hand-rolled cigarettes, pipes, or water pipes (bongs), however it can be used in vaporisers, turned into a tea, or used as an ingredient in foods as an edible. The THC in marijuana is responsible for changing how the brain works, by distorting how the mind perceives the world and making the heart beat faster. In particular marijuana is used to heighten perception, affect mood, and feel relaxed: it alters senses, sense of time,

Hair testing, however, is a different matter, particularly with passive exposure to crack/cocaine, which can deposit onto hair and be readily incorporated into it. With regards to cannabis, however, typically only metabolites (produced by the body and thus not found in smoke) are tested rather than THC, so failure is unlikely to result from non-extreme passive exposure. Niacin, also known as Vitamin B3, is speciously claimed by some to "burn it out" of one's system when taken at high doses (250–500 mg per day). While some Internet

Exposure to marijuana may have biologically-based physical, mental, behavioral and social health consequences and is "associated with diseases of the liver (particularly with co-existing hepatitis C), lungs, heart, eyesight and vasculature" according to a 2013 literature review by Gordon and colleagues. The association with these diseases has only been reported in cases where people have smoked cannabis.

Poppy seed-filled "pastries" (such as hamantashen or kolaches), contain enough opiates to potentially cause a false positive test result, even when a fairly high cutoff level is used. However, drug tests rarely screen for the actual drug used; instead they detect metabolites or increased enzyme levels as markers indicative of drug use. When substance use has been established (and the drug type, i.e. opiate or amphetamine), one can then be tested to

Jimson weed is highly toxic and can cause delirium, confusion, hallucinations, blurred vision, photophobia, dry mouth, urinary retention, hyperthermia, incoordination, hypertension, and rapid heartbeat among other effects.

Similar claims have been made in web forums on that topic. However, a 2013 study conducted by researchers at the University of Utah School of Medicine refute the possibility of self-administered zinc producing false-negative urine drug tests. Common known pharmaceutical drugs which cause false positives in instant THC dip tests include: The Duquenois–Levine test is a simple chemical color reaction test initially developed in the 1930s by Pierre Duquénois. To administer the test, a police

One possible way of minimizing the risks of spotting marijuana is using cooler knives, leading to the tetrahydrocannabinol (THC) being vaporised rather than the entire plant matter being burnt. Some users also fill the lower half of the spottle with ice (that stays in place by being frozen to the edges of the spottle), but much more common is to just freeze the bottle, which leads to a cooler smoke that is less harsh on the lungs. Care must

Marijuana, also known as cannabis, is a euphoriant and hallucinogenic drug prepared from the dried leaves of the strong-smelling plant "Cannabis sativa". Marijuana is the most commonly used illicit drug. Also, since it consists of the dried leaves of the hemp plant; smoked or chewed for euphoric effect, it is considered a "soft" drug. Side effects for street drugs vary. Yet side effects for marijuana are: psychological dependence requiring more of the drug to get the same effect, sleepiness, difficulty keeping track of time, impaired or reduced short-term memory, reduced

As a result, the DEA has recommended that officers not field test drugs if fentanyl is suspected, but instead collect and send samples to a laboratory for analysis. "Exposure via inhalation or skin absorption can be deadly," they state. Over a two-year period, close to $800 million worth of fentanyl pills were illegally sold online to the U.S. by Chinese distributors.

A marijuana withdrawal syndrome occurs, consisting of anxiety, depression, sleep and appetite disturbances, irritability, tremors, diaphoresis, nausea, muscle convulsions, and restlessness. Often, persons using marijuana erroneously believe that the drug is helping them combat these symptoms without realizing that actually marijuana is the cause of these effects. Therefore, when a patient anecdotally reports a drug to have medicinal value, this must be followed by objective scientific studies." The US Drug Enforcement Administration also says: Most of the psychoactive drugs now prohibited in modern societies have had medical uses in history. In natural plant drugs like opium, coca,

Drugs such as cocaine, heroin, marijuana, and methamphetamine are related to a wide range of paraphernalia. Paraphernalia generally falls into two categories: user-specific products and dealer-specific products. User-specific products include glass hashish pipes, crack cocaine pipes, smoking masks, hashish bongs, cocaine freebase kits, syringes, roach clips for holding the burning end of a marijuana joint. Some stores sell items for growing hydroponic marijuana, such as guidebooks, fertilizer, and fluorescent grow-lights. The term "paraphernalia"

Dealers who do so often (but not always) advertise their wares as being "enhanced" with other substances, and charge more money than they would otherwise, even if they do not say exactly what the lacing agents are. Such concoctions are often called "fry", "wet", "illy", "sherm", "water-water", "dust(ed)", "super weed", "grecodine" or other names. Black market ecstasy pills are frequently found to contain other drugs in place of or in addition to methylenedioxymethylamphetamine (MDMA).
