Dissociatives are a class of hallucinogen which distort perceptions of sound and sight and create emotions of detachment - dissociation - from the environment itself. This is done by reducing or blocking signals in the conscious mind from other portions of the brain. Even though lots of types of drugs are capable of such an action, dissociatives are exceptional because they do so in such a manner that they produce effects, which might include sensory deprivation, dissociation, hallucinations, and vision such as conditions or trances. Some, that are non-selective in action and affect dopamine and/or opioid systems, might be capable of inducing euphoria.
Dissociatives have depressant effects and may create sedation, respiratory depression, analgesia, anesthesia, and ataxia, as well as cognitive and memory impairment and amnesia.
