This article is about the class of hallucinogen. For the psychological state, see Dissociation (psychology). For the Australian band, see The Dissociatives. For other uses, see Dissociation.

Dissociatives are a class of hallucinogen, which distort perceptions of sight and sound and produce feelings of detachment - dissociation - from the environment and self. This is done through reducing or blocking signals to the conscious mind from other parts of the brain.[1] Although many kinds of drugs are capable of such action, dissociatives are unique in that they do so in such a way that they produce hallucinogenic effects, which may include sensory deprivation, dissociation, hallucinations, and dream-like states or trances.[2] Some, which are nonselective in action and affect the dopamine[3] and/or opioid[4] systems, may be capable of inducing euphoria. Many dissociatives have general depressant effects and can produce sedation, respiratory depression[citation needed], analgesia, anesthesia, and ataxia, as well as cognitive and memory impairment and amnesia.[citation needed]

Classes of dissociatives[edit]

NMDA receptor antagonists[edit]

κ-opioid receptor agonists[edit]

Effects[edit]

The effects of dissociatives can include sensory dissociation, hallucinations, mania, catalepsy, analgesia and amnesia.[9][10][11] The characteristic features of dissociative anesthesia were described as catalepsy, amnesia and analgesia.[9] According to Pender (1972), "the state has been designated as dissociative anesthesia since the patient truly seems disassociated from his environment."[12] Bonta (2004) described dissociative anaesthesia as "... a peculiar anaesthetic state in which marked sensory loss and analgesia as well as amnesia is not accompanied by actual loss of consciousness."[13] Both Pender (1970) and Johnstone et al. (1959) reported that patients under anesthesia due to either ketamine or phencyclidine were prone to purposeless movements and had hallucinations (or "dreams"[14]) during and after anesthesia. Some patients found the hallucinations euphoric while others found them disturbing.

At sub-anesthetic doses, dissociatives alter many of the same cognitive and perceptual processes affected by other hallucinogenic drugs such as mescaline, LSD, and psilocybin; hence they are also considered hallucinogenic, and psychedelic.[15][16][17][18] Perhaps the most significant subjective differences between dissociatives and the classical hallucinogens (such as LSD and mescaline) are the dissociative effects, including: depersonalization, the feeling of being unreal, disconnected from one's self, or unable to control one's actions; and derealization, the feeling that the outside world is unreal or that one is dreaming.[19]
