LSD (Lysergic acid diethylamide) is a Class A drug made from ergot, a fungus found growing on grass.
LSD is a white powder but is usually sold as blotting paper or gelatine squares which have been soaked in a solution of the drug and often have a design or pattern on them. The LSD solution can sometimes be dropped onto sugar cubes.
The squares are swallowed.
The effects usually begin after thirty minutes and can last up to twelve hours. It causes hallucinations including intensified colours, changes in sounds and in the sense of time and intense emotional reactions. People who are already anxious or depressed may have unpleasant or frightening experiences (a bad trip). The effects also depend on the strength of the drug taken, which can vary from dose to dose.
Hallucinations and the effects of the drug on people's judgement may cause accidents or make them think they can do impossible things, like flying.
Withdrawal symptoms may last for several days and you may feel withdrawn or emotional. You may have flashbacks - repeats of the experiences during the trip.
LSD is not physically addictive but users may become dependent
on the feelings LSD gives them. Life may seem very ordinary
and boring
without
the stimulation
form the drug. Flashbacks may occur for several years afterwards,
perhaps in a different form from what you experienced on
the trip itself. Constant
use
can lead people to be out of touch with the real world.
