Cyclic vomiting syndrome and marijuana use

Marijuana use can trigger recurrent cyclic vomiting in teenagers. A new report points out that 1 known cause of cyclic vomiting syndrome (CVS) is chronic use of cannabis. Cyclic vomiting syndrome is a constellation of recurrent vomiting, nausea, and abdominal pain. When linked to chronic marijuana use, CVS has the unique characteristic of being temporarily relieved by frequent hot showers. The researchers recommend screening for marijuana use by history and a urine drug screen in adolescents with CVS who take hot showers for symptomatic relief (Sawni A, et al. Clin Pediatr. 2016;55[6]:560-563).
