Desired Effects:Hallucinations, hilarity. LSD's psychological effects (referred to as a "trip") can be unpredictable and random as it will vary greatly from person to person, depending on factors such as previous experiences, state of mind and environment, as well as dose strength.
Side Effects:Confusion, disorientation, loss of coordination, distortions in time and space.
Long term risks:Release or triggering of underlying psychological problems, flashbacks.
Short term risks:Accidents, anxiety, emotional distress or 'bad trip'. A bad trip refers to a disturbing hallucinogenic experience that can cause users to feel extremely anxious and threatened. As an LSD experience can last between 6-12 hours - depending on dosage, tolerance, body weight and age - this can feel like a very lengthy unpleasant experience.
It is cheap (around £1 - £5 each), easy both to conceal and to use.
