LSD Flashbacks

A patient with no history of LSD ingestion reported 14 of 16 visual symptoms characteristic of LSD flashbacks, including persistent visual distortions that began during a near-psychotic episode at age 17 and continued for 20 years with decreased frequency. Short trials of two neuroleptics (thiothixene and trifluoperazine hydrochloride) increased her symptoms. This case suggests that the visual phenomenology associated with LSD flashbacks can occur without prior hallucinogen exposure, arising instead from a psychotic episode.
