Hallucinogens and Dissociatives

Abstract Hallucinogens, also referred to as psychedelics, are a broad range of agents that alter perception in different ways. An estimated 1.3 million Americans are current (past month) users of hallucinogens. Hallucinogen use is highest among young adults; 3,4-methylenedioxymethamphetamine (MDMA) is the most commonly used agent, followed by lysergic acid diethylamide (LSD) and phencyclidine (PCP). Hallucinogens alter sensory perception and change the qualities of thought or emotion. PCP, MDMA, and LSD can be detected in urine drug tests. There appear to be few serious lasting complications associated with hallucinogen use. There are few data on the treatment of individuals who use hallucinogens or dissociatives.
