On April 19, 1943, Dr. Albert Hofmann dosed himself with 0.25 mg of d-lysergic acid diethylamide tartrate, which he had accidentally ingested a few days earlier, and took his storied bike ride through the streets of Basel, Switzerland. A generation later the substance, abbreviated as LSD, fueled a cultural revolution despite criminalization in 1965. (LSD's social history can be read in Jay Stevens's 1987 Storming Heaven.) The most potent of all psychedelics, LSD is usually ingested orally on blotter paper frequently festooned with cultural icons. While the typical late-'60s tripper probably took around 250 mg of acid, the average strength of the hits sold in recent years, known to old-timers as "disco doses," is less than half that. LSD embodies a potentially infinate array of effects, ranging from mild sensory distortions to peak religious experiences. It is essentially a boundary-dissolving, experience-enhancing substance-as with most psychedelics, the effects are tied to the mind-set of the user and the setting in which it is ingested.
