Cannabinoid hyperemesis syndrome is characterized by recurrent nausea, vomiting and colicky abdominal pain. These symptoms have been reported to be alleviated temporarily by taking a hot shower or bath or more permanently by abstaining from the use of cannabis. The syndrome was described by Allen and colleagues (2004), and Sontineni and colleagues (2009) who offer simplified clinical diagnostic criteria. A subsequent, larger study reported a case series of 98 subjects with cannabinoid hyperemesis syndrome, confirming the earlier reported findings. This is only a proposed disorder as it is currently unlisted in the World Health Organisation International Classification of Diseases. ==Signs and symptoms== The long-term and short-term effects of cannabis use are associated with behavioural effects leading to a wide variety of effects on the body systems and physiologic states.〔 The phenomenon of cannabinoid hyperemesis and clinical diagnosis remained obscure until recently. In spite of these early reports, uncertainty remained among the doctors and scientists regarding the existence of the cannabinoid hyperemesis syndrome. Sontineni and colleagues (2009) discuss the cannabinoid hyperemesis syndrome to offer guidelines for the clinical diagnosis.〔 The "suggested criteria for the diagnosis" are: ''Essential feature'': 1) history of regular cannabis use for years; ''Major'' clinical features of syndrome: 2) severe nausea and vomiting, 3) vomiting that recurs in a cyclic pattern over months and 4) resolution of symptoms after stopping cannabis use. In addition diagnosis has ''supportive features'' of - 1) compulsive hot baths with symptom relief; 2) colicky abdominal pain; and 3) no evidence of gall bladder or pancreatic inflammation. Since the publication of these clinical guidelines, the syndrome is more easily recognized and treated. A series of 98 cases and review suggested modifications to original set of criteria that are listed below.
