Lsd

LSD: Produced in laboratories in the United States, this is the most potent hallucinogen known to science and is generally sold in the form of impregnated paper typically imprinted with colorful graphic designs. It has also been found in tablets (microdots), thin squares of gelatin (window panes), in sugar cubes, and rarely in liquid form. During the first hour after ingestion, users may experience visual changes with extreme changes in mood.

While hallucinating, the user may suffer impaired depth and time perception accompanied by distorted perception of the shape and size of objects, movements, colors, sound, touch and the user's own body image. The ability to make sound judgments and see common dangers is impaired, making the user susceptible to personal injury. It is possible for users to suffer acute anxiety and depression after an LSD "trip"and flashbacks have been reported days, and even months, after taking the last dose. DEA enforcement operations have made a dramatic difference in reducing the supply of LSD throughout the United States.
