Mushrooms (Psilocybin) are obtained from certain mushrooms found in South America, Mexico, and the U.S, although the substance can also be produced synthetically. Mushrooms containing psilocybin are available fresh or dried with long, narrow stems topped by caps with dark gills on the underside. These mushrooms are usually ingested orally, but can also be brewed in a tea or added to food to mask the bitter flavor. Once ingested, psilocybin is broken down in the user's body to produce psilocyn, another hallucinogenic substance.
