Objective: This paper describes a case of cannabinoid hyperemesis, a curious, emerging condition associated with long-term cannabis abuse. The authors wish to facilitate its recognition and management by clinicians.
Conclusions: Cannabinoid hyperemesis is a cluster of symptoms characterized by chronic cannabis abuse, cyclical vomiting and compulsive bathing behaviours. The condition can be missed unless an adequate history is taken of illicit drug ingestion. It can be confused with obsessive-compulsive disorder. The treatment consists of supportive measures in the acute phase, followed by complete abstinence from cannabis.
