There are dozens of types of mushrooms: legal, edible and harmless.  However, mushrooms belonging to the psilocybin species (“magic mushrooms) are nearly all-small brown or tan mushrooms that are easily mistaken for any number of non-psychoactive inedible or poisonous mushrooms in the wild.  Psilocybin mushrooms are illegal in the United States because they contain psilocybin and psilocin, which are specifically listed as illegal.

 Psilocybe mushrooms have been used for generations by Native Americans in Central and South America .  The mistaken impression that the experience of using mushrooms is harmless is far from the truth.

The primary effects of the ingestion of these mushrooms is psychedelic.  Like other materials of this type, the chemicals in the mushrooms react with prescribed medication (such as MAOIs) and have been known to trigger latent psychiatric problems.  Use of these products has been shown to be especially dangerous for those with a family history of depression or schizophrenia or early onset mental illness.  Similar, although usually less intense, to LSD experiences the potential for negative hallucinations is high. 

Slang terms: mushrooms, magic mushrooms, mushies, shrooms, psiloybes, cubes, and liberty caps.
