A former hallucinogen user is experiencing symptoms similar to intoxication a year after quitting. What is this condition called?

The condition experienced by a former hallucinogen user, characterized by symptoms similar to intoxication long after cessation of use, is accurately identified as Hallucinogen Persisting Perception Disorder. This disorder is specifically associated with the continued presence of perceptual disturbances akin to those experienced during hallucinogen intoxication, such as visual alterations, flashbacks, or other sensory anomalies.

The key aspect of this disorder is that these symptoms can persist long after the drug has been eliminated from the body, often causing significant distress or impairment in social, occupational, or other areas of functioning. This distinguishes it from other potential conditions, as the symptoms originate from prior hallucinogen use rather than being triggered by other means.

With respect to other options, Substance-Induced Psychotic Disorder typically involves acute or subacute psychotic symptoms induced by a substance, which would not apply here since the symptoms are occurring a year after stopping use. Post-Acute Withdrawal Syndrome encompasses a range of symptoms following cessation of use but would generally not include persistent perceptual disturbances. Psychotic Spectrum Disorder is a broader term that does not specifically relate to hallucinogen use or its lingering effects. Therefore, Hallucinogen Persisting Perception Disorder is the most contextually fitting and accurate answer
