Effects

Users refer to their hallucinatory experience with LSD as a “trip” and to acute adverse reactions as a “bad trip.” These experiences are long, and typically they begin to clear after about 12 hours. Some LSD users experience severe, terrifying thoughts and feelings, such as fear of losing control, fear of insanity and death, and despair while using LSD. Some fatal accidents have occurred during states of LSD intoxication.
