Haloperidol Versus Ondansetron for Cannabis Hyperemesis Syndrome (HaVOC)

Summary

Cannabis Hyperemesis Syndrome (CHS) has become a well-documented syndrome since 2004 and is expected to increase in prevalence with continuing liberalization of marijuana and recognition of the disease. Regardless of whether the association with heavy cannabis use is recognized, there is well-documented resistance to traditional anti-emetic treatment. Given promising reports of the use of intravenous haloperidol, a randomized controlled trial comparing it to the commonly administered anti-emetic ondansetron will contribute to the management of CHS
