LSD (lysergic acid diethylamide) is a synthetic (man-made) drug that has been abused for its hallucinogenic properties since the 1960s. If consumed in a sufficiently large dose, LSD produces delusions and visual hallucinations that distort the user's sense of time and identity.
LSD typically is sold as a liquid or applied to blotter paper, sugar cubes, gelatin squares, and tablets.
LSD generally is taken by mouth. The drug is colorless and odorless but has a slightly bitter taste.
Individuals of all ages use LSD. Data reported in the National Household Survey on Drug Abuse indicate that an estimated 20.2 million U.S. residents aged 12 and older used LSD at least once in their lifetime.
The effects associated with LSD use are unpredictable and depend upon the amount taken, the surroundings in which the drug is used, and the user's personality, mood, and expectations. Some LSD users experience a feeling of despair, while others report terrifying fears--of losing control, going insane, or dying. Some users have suffered fatal accidents while under the influence of LSD.
LSD users often have flashbacks, during which certain aspects of their LSD experience recur even though they have stopped taking the drug. In addition, LSD users may develop long-lasting psychoses, such as schizophrenia or severe depression.
LSD is not considered an addictive drug--that is, it does not produce compulsive drug-seeking behavior as cocaine, heroin, and methamphetamine do. However, LSD users may develop tolerance to the drug, meaning that they must consume progressively larger doses of the drug in order to continue to experience the hallucinogenic effects that they seek
The most common names for LSD are acid, boomers, and yellow sunshine.
