LSD is still one of the most potent mood-changing chemicals and is derived from the extremely poisonous ergot fungus, a mold which grows on rye and other grains. Its effects are unpredictable. A tiny amount can produce 12 hours or more of effects.
LSD is sold in tablets, capsules or in liquid form. It is commonly added to absorbent paper and divided into small decorated squares. Each square is a dose.
Dilated pupils, higher body temperature, increased heart rate and blood pressure, sweating, loss of appetite, sleeplessness, dry mouth and tremors. People can experience severe, terrifying thoughts and feelings, fear of losing control, fear of insanity and death and feelings of despair while using LSD.
Flashbacks, or recurrences, of an LSD “trip” can be experienced long after the drug is taken and its effect has apparently worn off. The “trip” itself usually begins to clear up after about 12 hours, but some users manifest long-lasting psychoses.
