Topic

Lysergic acid diethylamide, commonly known as LSD or acid, is a potent semisynthetic psychedelic drug derived from ergot. It is well known for its psychological effects, which include altered thinking processes, closed- and open-eye visuals, synesthesia, and an altered sense of time. First synthesized by Swiss chemist Albert Hofmann in 1938, it played a significant role in 1960s counterculture and remains a subject of medical and psychological research.
