LSD is the most common hallucinogen and is one of the most potent mood-changing chemicals. It is manufactured from lysergic acid, which is found in ergot, a fungus that grows on rye and other grains. LSD is usually found on “blotter” paper (paper that is perforated into small squares). The squares or “tabs” may be colored or have images printed on them. Liquid LSD is a clear liquid, usually in a small container, tube or flask.
LSD can also be found in thin squares of gelatin. The effects of LSD are unpredictable, and occur based on factors such as on the amount taken, the user’s personality, mood, expectations and the surroundings in which the drug is used. The physical effects include dilated pupils, higher body temperature, increased heart rate and blood pressure, sweating, loss of appetite, sleeplessness, dry mouth and tremors. Sensations and feelings change much more dramatically than the physical signs. The user may feel several different emotions at once or swing rapidly from one emotion to another. If taken in a large enough dose, the drug produces delusions and visual hallucinations. The user’s sense of time and self changes. Sensations may seem to “cross over,” giving the user the feeling of hearing colors and seeing sounds. These changes can be frightening and can cause panic.
