Lysergic acid diethylamide (abbreviated as LSD or LSD-25) is a semisynthetic psychedelic substance of the lysergamide family. LSD was first synthesized by Albert Hoffmann in Switzerland in 1938 from ergotamine, a chemical from the fungus ergot. Hoffmann accidentally discovered its psychedelic effect in 1943.
