A Case of Cannabis Use-Associated Psychotic Disorder Accompanied by Autoscopic Phenomena

Cannabis (Marijuana) is one of the most commonly used illegal addictive substances. The psychiatric symptoms associated with cannabis use are agitation, insomnia, depressive or raised mood, anxiety, hallucinations, and concentration problems. It is known that cannabis use increases the risk for psychoses and bipolar disorders and may deteriorate the clinical presentation of pre-existing psychoses and bipolar disorders. A characteristic symptom of autoscopic psychosis is visual hallucination of some part or the entirety of a person’s body, imitating his or her behaviors and being perceived as if seen in a mirror. This is not a specific symptom of any mental disorder and the cause is not definitively known. In this case presentation, the symptoms of a patient diagnosed with cannabis use-associated autoscopic psychosis are discussed in the context of the literature.
