Background

d-lysergic acid diethylamide, more commonly known as LSD, was first synthesized in 1938 by the chemist Albert Hofmann in efforts to chemically create a blood stimulant.[1]In 1943, Hoffman accidently ingested LSD for the first time, discovering its hallucinagenic properties, reportedly seeing "an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopelike play of colors." LSD became very popular in the 1960's and 1970's, making it a very important part of the "counterculture" movement, encouraging participants to "turn on, tune in, drop out."

Mechanism

Serotonin like agent
