LSD is a tasteless, odorless, colorless white powder that can be made into tablets, capsules, or even a liquid to be injected. A user usually can feel the effects 30-90 minutes after doing it, and the effects can last up to twelve hours. LSD, or Lysergic acid Diethylamide, was originally synthesized in 1938 by Dr. Albert Hoffman, but its hallucinogenic effects were unknown until 1948 when Dr. Hoffman accidentally consumed some. Decades ago, LSD was used as a research tool to study mental illness because it has structural similarity to a chemical presence in brain and because of the similarity of its effects to certain aspects of psychosis. When taken as a hallucinogen, the effects of LSD can be extremely powerful.
Effects are unpredictable, depending on the amount taken.
Some physical effects include sweating, dizziness, loss of appetite, sleeplessness, dry mouth, tremors, rises in body temperature, heart rate, and blood pressure, and dilated pupils. Some mental effects are that the user's mind can change rapidly from one wild emotion to the next. They feel pressure, confusion, anxiety, or they can also feel like their lives are out of control. Personality, mood, and emotions also change dramatically. LSD is often used at concerts and at all-night raves.
