Magic mushrooms are wild or cultivated mushrooms that contain psilocybin, a naturally-occurring psychoactive and hallucinogenic compound. Psilocybin is considered one of the most well-known psychedelics, according to the Substance Abuse and Mental Health Services Administrations. Psilocybin is classified as a Schedule I drug, meaning that has a high potential for misuse and has no currently accepted medical use in treatment in the United States. Although certain cultures have known to use the hallucinogenic properties of some mushrooms for centuries, psilocybin was first isolated in 1958 by Dr. Albert Hofmann, who also discovered lysergic acid diethylamide (LSD). Magic mushrooms are often prepared by drying and are eaten by being mixed into food or drinks, although some people eat freshly picked magic mushrooms.
