Cannabis-induced psychotic disorder with onset during withdrawal: a brief report of emerging evidence

Clinical Diagnosis and Management of Gradual Onset Cannabis-Induced Psychosis Following the Consumption of Delta-8-Tetrahydrocannabinol

Cannabis-induced psychosis (CIP) is an increasingly acknowledged psychiatric phenomenon observed in vulnerable patients exposed to cannabis. This brief case report details a male patient in his 20s, who presents to the ED with derealization two days after ingesting a gummy worm containing delta-8-tetrahydrocannabinol (Δ8-THC). Two days post-ED discharge, the patient gradually developed symptoms of religious-themed psychosis and was prescribed 10 mg of aripiprazole daily. The patient seemingly recovered within four days of starting treatment. This paper contributes to the limited literature pertaining to CIP and discusses implications for diagnostics and treatment in the ED setting.
