urbane mitove o marijuani po meni su informacije i više nego dobre
...
ako mislite da nespada ovo ovdje molim premjestite.

Marijuana laced with LSD
There is a myth that low quality marijuana may be dipped in LSD to increase its potency or make the user hallucinate upon smoking. However, LSD rapidly degrades in the presence of moisture or heat. LSD cannot be smoked; it will be destroyed at a temperature of 80°C, well below the minimum 180°C required to release the
THC in marijuana.
This is a common misconception. The marijuana is actually soaked in formaldehyde giving PCP like effects. Knows and wet on the street.
[edit] Urban legends about cannabis
For further information about the toxicity of cannabis, see Tetrahydrocannabinol toxicity. Many misleading urban legends about
cannabis exist. Like
LSD rumors, many were spread by
anti-drug groups during the 1960s and are believed to continuously circulate today. These widespread legends claim that it is easy to
overdose on the smokable variant of cannabis and that it is extremely dangerous and addictive when compared to
alcohol and
nicotine, when in fact alcohol and nicotine, the drugs that are claimed to be safer, are actually considered by many to be
hard drugs (or borderline) and both can be very addictive. Furthermore, scaling up from animal studies, an average human would need to ingest about 1.8 kg of cannabis to overdose. Cannabis is not
physically addictive, but
can be (like all things)
psychologically addictive, though this form of addiction tends to occur only after someone has been using the drug habitually.
[10][11][12][13] Also, there are studies that show no actual increased risk of cancer from smoking marijuana, even when duration of use is expanded over several years (this could be because THC allows cells to die faster).
[14] In fact, some studies indicate
THC to have anticancer properties, with studies showing tumor reduction in mice.
[15]
[edit] Amotivational Syndrome
Amotivational syndrome or 'burnout' is a proposed condition often cited by many anti-drug organizations as common, with claimed symptoms which range from lethargy to a lack of motivation. There is no medical basis or evidence for this condition and some studies have been conducted showing this claim to be false. Though marijuana smoking is not physically addictive, there is a possibility of a psychological addiction which therefore may divert motivation.
[16][17][18][19]
[edit] Memory loss or damage
Another claim by many anti-drug organizations is that marijuana smoking causes memory loss or damage. While intoxicated or 'high' there is short-term memory loss but long term, persistent memory loss has not been found conclusively in any rigorous, carefully controlled scientific study.
[20]
[edit] Multi-day impairment
Another claim by anti-drug organizations about cannabis is that impairment due to smoking it lasts many days after using it since THC is stored in the fat cells, leading to a low-grade haze long after the primary high is gone. This myth is based primarily on anecdotal evidence and the fact that urine drug tests remain positive for at least several days after using, and longer for regular users. But the drug tests measure non-psychoactive metabolites, not active THC. And the blood levels of THC generally fall well below the psychoactive threshold within 2-4 hours of use. Driving impairment generally lasts 2-6 hours after smoking, though unusually high doses may last longer. A cannabis equivalent of a hangover may occur the morning after taking high doses, but even that ends much sooner than the legend suggests. While someone who smokes cannabis on Friday night would most likely fail a urine test on Monday morning, they would no longer actually be impaired by that point.
[edit] Jimson weed
Jimson weed, or
Datura stramonium, is an entirely unrelated, relatively toxic plant that can be used medicinally, or recreationally as a
deliriant and potent hallucinogen. A myth originated in the 1960s that Cannabis and Jimson weed were the same plant.[
citation needed] Allegedly, it was cannabis, and not Jimson weed, which when eaten by cattle would cause stampedes. Aside from the word "weed," a slang term for cannabis, there is no connection between the two plants. Jimson weed can be dangerous or even deadly, as its effects are unpredictable with unpleasant side effects, and it is very easy to overdose on. Jimson weed was never declared a controlled substance, perhaps due to its relative unpopularity as a recreational drug.
[edit] Reefer Madness
Originating in the 1930s, this myth was the basis for films like
Reefer Madness, and used by
Harry Anslinger of the
Federal Bureau of Narcotics as justification for outlawing cannabis. The allegation was that even the calmest, most normal person could be transformed into a psychopathic killer or rapist solely from smoking a joint. This legend often had racial overtones as well, such as black men getting high and raping white women. No causal relationship has ever been proven linking such crimes to the acute intoxication of cannabis alone. For example, studies of the Jamaican working class showed no difference in the crime rates between users and nonusers of cannabis.
