Abstract
Abstract The recurrence of flashbacks without acute or chronic hallucinogen consumption has been recognized in the DSM IV criteria as the hallucinogen persisting perception disorder (HPPD). Perceptual disturbances may last for 5 years or more and represent a real psychosocial distress. We reported here a case of a 18-year-old young man presenting HPPD after a mixed intoxication with psylocibin and cannabis. This report shows symptomatic recurrences persisting more than 8 months. Various differential diagnoses were evoked and our therapeutic strategies were described.
