Signs and Symptoms of Hallucinogen Abuse (LSD, Mescaline):

With the exception of PCP, all hallucinogens seem to share common effects of use. Any portion of sensory perceptions may be altered to varying degrees. The "seeing" of sounds, and the "hearing" of colors, is a common side effect of hallucinogen use. Depersonalization, acute anxiety, and acute depression have also been noted as a result of hallucinogen abuse.
