The active chemical in magic mushrooms that produces hallucinations.

A hallucinigenic compound found in various strains of magic mushrooms (native to many countries in England). Very potent, producing an intense trip. Typically, the trip lasts around 4-6 hours. It is a psychedelic trip with many colors and shape shifting, ect. Often one will have a rather philosophic come down (the stage of the trip where the effects are wearing off).

A drug when taken many strange things will happen

Even worse when combined with Salvia Divinorum
