Hallucinogens

Lysergic acid diethylamide, LSD, LSD-25, or acid, is a semisynthetic psychedelic drug of the ergoline family. Probably the best known psychedelic, it has been used mainly as a recreational drug, an entheogen, and a tool to supplement various practices for transcendence, including in meditation, psychonautics, art projects, and illicit (though at one time legal) psychedelic psychotherapy, whether self-administered or not. It is synthesized from lysergic acid derived from ergot, a grain fungus that typically grows on rye and was first synthesized by Swiss chemist Albert Hofmann. The short form LSD comes from its early codename LSD-25, which is an abbreviation for the German "Lysergsдure-diethylamid" followed by a sequential number.[1][2]
