Also known as Acid, Blotter, Dots, and Yellow Sunshine.

LSD is one of the most powerful mood-changing chemicals. It is a clear or white odorless material made from lysergic acid, which is found in a fungus that grows on rye and other grains.

LSD is sold on the street in small tablets (“microdots”), capsules or gelatin squares (“window panes”). It is sometimes added to absorbent paper, which is then divided into small squares decorated with designs or cartoon characters (“loony toons”). Occasionally it is sold in liquid form. But no matter what form it comes in, LSD leads the user to the same place—a serious disconnection from reality.

LSD users call an LSD experience a “trip,” which can consist of vocal and physical hallucinations, altered reality, and suicidal ideation, typically lasting twelve hours or so. When things go wrong, which often happens, it is called a “bad trip,” and in some cases can cause the person to go into a state of psychosis or lead to hospitalization.
