A hot bath to calm what ails you: the Cannabis Hyperemesis Syndrome

Acute Med. 2012;11(1):23-4.


The Cannabis Hyperemesis Syndrome (CHS) defines a recently described paradoxical association between recurrent vomiting episodes, daily cannabis excess and symptomatic relief with a hot bath or shower. Importantly, symptom resolution only occurs with cessation of cannabis use. We describe a case of CHS which had resulted in repeated hospital admissions. As cannabis use is common, it is important for both patients and Acute Physicians to be aware of this increasingly recognised condition.
