A hot mess: A case of hyperemesis. Cheung E et al. Can Fam Physician 2014 Jul;60:633-637.
With medical marijuana now legal in 23 states plus the District of Columbia, and recreational marijuana legal in 2 states, it is essential that all emergency and primary care physicians become familiar with the adverse effects that can ensue from regular use of cannabis.
One of the most striking and unexpected complications of chronic cannabis exposure is violent cyclic vomiting. This has been called “cannabinoid hyperemesis syndrome” (CHS). In this review article, the authors propose the following criteria of CHS:
- Chronic regular use of marijuana
- Cyclic nausea and vomiting with or without abdominal pain
- Relief of symptoms by taking hot baths or showers
- Lack of alternative cause
- Resolution of symptoms within days of abstinence
- Return of symptoms on re-exposure to cannabinoid products
This short review is worth reading, especially for those unfamiliar with this often unrecognized syndrome.
