LSD is one of the most powerful hallucinogens in the world. It is sold on the streets in small tablets, capsules, or blotting paper (“window panes”).
The mood-altering effects of LSD are unpredictable, ranging from a spaced-out “bliss” –which users often mistake for enlightenment—with visual disturbances to feelings of intense terror. The LSD experience is sometimes called a “trip,” which can last up to 12 hours. Users also develop tolerance on LSD, which increases both the physical effects and the risk of flashbacks or a “bad trip.”
