Question

A common adverse effect of chronic recreational marijuana use is cannabinoid hyperemesis syndrome. In fact, cannabinoid hyperemesis syndrome is a near daily diagnosis in many Canadian emergency departments. Anecdotal evidence supports the use of haloperidol to treat the symptoms of cannabinoid hyperemesis syndrome. Is haloperidol more effective than odansetron for the treatment of the nausea and vomiting associated with cannabinoid hyperemesis syndrome?
