title: [Cyclical hyperemesis secondary to cannabis abuse].
abstract: Cannabinoid hyperemesis is characterized by recurring episodes of nausea and vomiting, with a stereotyped pattern, related to cannabis consumption. This syndrome is a paradoxical reaction to cannabis that develops in susceptible chronic cannabis users after several years of exposure. There is a direct relationship between cannabis use and the onset of the hyperemesis and between cessation of cannabis use and symptom resolution. The first cases were described in 2004. Since then, several new cases have been reported, although there are few studies of this syndrome. We report a case of chronic cannabis use with nausea and cyclic vomiting for 7 years. The symptoms were relieved by hot baths. A complete gastroenterological study was performed and no alterations were found. Cannabis use and its cessation are related to the presence or absence of the symptoms.
