[Cannabinoid hyperemesis syndrome causing prolonged nausea and vomiting in patients with cannabis abuse].

Cannabis is one of the most used drugs worldwide. The link between repeated episodes of nausea, vomiting, and cannabis abuse is often missed in patients with prolonged cannabis abuse and is named cannabinoid hyperemesis syndrome. Characteristically, the symptoms appear in a cyclical pattern and are relieved by long, hot baths. Physical examination, radiology and endoscopy are often normal. The symptoms resolve with cessation of cannabis abuse. Health professionals must be aware of this syndrome in order to detect the patients early and to avoid extensive medical workup.
