SUMMARYCannabis is the most widely used illicit drug in the world. The medicinal value of cannabis as an antiemetic is well known by the medical fraternity. A less wellrecognised entity is the potential for certain chronic users to develop hyperemesis. We describe the case of a young man who presented to us with features of cannabinoid hyperemesis syndrome. We review the current literature on this condition, its pathogenesis and management. BACKGROUND

CHS is an underappreciated cause of recurrent nausea and vomiting and is frequently misdiagnosed. Healthcare providers should have a low index of suspicion for diagnosing CHS and the clinical history in such patients should routinely include direct questioning on cannabis use. The prognosis is very good upon cessation of cannabis intake.

Provided that such innovations in sustainable skills teaching are deemed appropriate by clinical skills directors, such methods could be adopted across medical schools and expanded to cover a wider range of skills.
