Effects of Psilocybin

"The active compounds in psilocybin-containing 'magic' mushrooms have LSD-like properties and produce alterations of autonomic function, motor reflexes, behavior, and perception.³ The psychological consequences of psilocybin use include hallucinations, an altered perception of time, and an inability to discern fantasy from reality. Panic reactions and psychosis also may occur, particularly if a user ingests a large dose. Long-term effects such as flashbacks, risk of psychiatric illness, impaired memory, and tolerance have been described in case reports."
