LSD

Lysergic Acid Diethylamide-LSD

LSD is a hallucinogen. It induces abnormalities in sensory perceptions. The effects of LSD are unpredictable depending on the amount taken, on the surroundings in which the drug is used, and on the user's personality, mood, and expectations. LSD is typically taken by mouth. It is sold in tablet, capsule, and liquid forms as well as in pieces of blotter paper that have absorbed the drug.Typically an LSD user feels the effects of the drug 30 to 90 minutes after taking it. The physical effects include dilated pupils, higher body temperature, increased heart rate and blood pressure, sweating, loss of appetite, sleeplessness, dry mouth, and tremors. LSD users report numbness, weakness, or trembling, and nausea is common. There are two long-term disorders associated with LSD, persistent psychosis and hallucinogen persisting perception disorder which used to be called "flashbacks".
