LSD is a semisynthetic psychedelic of the lysergamide class, first synthesized by Albert Hofmann in 1938 from ergot alkaloids, with its psychoactive properties discovered in 1943. It is perhaps the most widely researched and culturally influential psychedelic substance, having played a central role in the 1960s counterculture movement. LSD is among the most potent psychoactive compounds known, producing effects at microgram doses. It is considered non-addictive with extremely low toxicity relative to dose.
