Magic mushrooms are mushrooms that contain psilocybin. Psilocybin is a psychedelic drug with effects similar to those of LSD when ingested. They are commonly referred to colloquially as magic mushrooms or just shrooms. They are either eaten raw, mixed with food, or brewed into a tea. Visions and revelations may be experienced and the effect can range from exhilarating to terrifying. Magic mushrooms, like all hallucinogens, can trigger underlying mental disorders and cause schizophrenic-type symptoms.
