Cannabinoid hyperemesis syndrome
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.[1][2] A subsequent, larger study reported a case series of 98 subjects with cannabinoid hyperemesis syndrome, confirming the earlier reported findings.[3] This is only a proposed disorder as it is currently unlisted in the World Health Organisation International Classification of Diseases.
