Hallucinogens can be divided into three broad categories: [[psychedelic drug|psychedelic]]s, [[dissociative]]s, and [[deliriant]]s. They can cause subjective changes in [[perception]], [[thought]], [[emotion]] and [[consciousness]]. Unlike other psychoactive drugs such as [[stimulants]] and [[opioids]], hallucinogens do not merely amplify familiar states of mind but also induce experiences that differ from those of ordinary consciousness, often compared to non-ordinary forms of consciousness such as [[trance]], [[meditation]], conversion experiences, and [[dream]]s.

Psychedelics, dissociatives, and deliriants have a long worldwide history of use within medicinal and religious traditions. They are used in [[shamanic]] forms of ritual [[healing]] and [[divination]], in [[initiation rites]], and in the religious rituals of [[syncretistic]] movements such as [[União do Vegetal]], [[Santo Daime]], [[Temple of the True Inner Light]], and the [[Native American Church]]. When used in religious practice, psychedelic drugs, as well as other substances like [[tobacco]], are referred to as [[entheogens]].

Hallucinogen-induced psychosis occurs when psychosis persists despite no longer being intoxicated with the drug. It is estimated that 26% of people with hallucinogen-induced psychosis will transition to a diagnosis of schizophrenia. This percentage is less than the psychosis transition rate for cannabis (34%) but higher than that of amphetamines (22%).<ref name="Transition of Substance-Induced, Br"/>

Starting in the mid-20th century, psychedelic drugs have been the object of extensive attention in the Western world. They have been and are being explored as potential therapeutic agents in treating [[clinical depression|depression]], [[post-traumatic stress disorder]], [[obsessive–compulsive disorder]], [[alcoholism]], and [[opioid addiction]]. Yet the most popular, and at the same time most stigmatized, use of psychedelics in Western culture has been associated with the search for direct [[religious experience]], enhanced [[creativity]], personal development, and "mind expansion". The use of psychedelic drugs was a major element of the 1960s [[counterculture]], where it became associated with various social movements and a general atmosphere of rebellion and strife between generations.
