LSD

D-lysergic acid diethylamide, commonly called acid, LSD, or LSD-25, is a powerful semisynthetic psychedelic drug. A typical dose of LSD is only 100 to 150 micrograms, a tiny amount roughly equal to one-tenth the weight of a grain of sand. Threshold effects can be felt with as little as 20 micrograms. LSD causes a powerful intensification and alteration of senses, feelings, memories, and self-awareness for 6 to 14 hours. In addition, LSD usually produces visual effects such as moving geometric patterns, "trails" behind moving objects, and brilliant colors. LSD usually does not produce hallucinations in the strict sense, but instead illusions and vivid daydream-like fantasies. At higher concentrations it can cause synaesthesia.

LSD is synthesized from lysergic acid and is sensitive to oxygen, ultraviolet light, and chlorine, especially in solution. However its potency may last years if stored away from light and moisture in a freezer. In pure form it is colorless, odorless, and bitter. LSD is typically delivered orally, usually on a substrate such as absorbent blotter paper, a sugarcube, or gelatin. In all these preparations, LSD is tasteless.

Introduced by Sandoz as a drug with various psychiatric uses, LSD quickly became a therapeutic agent that appeared to show great promise. However, the extra-medical use of the drug in western society in the middle years of the twentieth century led to a political firestorm that resulted in the banning of the substance for medical as well as recreational and spiritual uses.
