Patients presenting to the Emergency Department with nausea, vomiting and/or abdominal pain with a significant history of cannabis use and symptoms in a cyclic pattern will be assessed for study inclusion. After given written informed consent, patients will be treated with droperidol and diphenhydramine and symptoms will be assessed using a visual analog scale at time intervals up to 120 minutes. Patient will then be contacted at 24 and 48 hour intervals to assess symptoms on the same scale. This is a multicenter, prospective interventional study with results compared to a historical cohort using haloperidol.
