People who have an affinity for marijuana may be in for a big surprise, as reports of a new marijuana-related illness are on the rise. Cannabinoid hyperemesis syndrome, or CHS, is a disease acquired through chronic marijuana use. CHS is characterized by cyclic episodes of nausea and vomiting. Hot showers appear to be the only remedy for those suffering from the symptoms of CHS, and it has become the key warning sign for physicians trying to diagnose the syndrome.

Physicians say that patients will come in to emergency departments three or four times before getting a correct diagnoses, because the symptoms are not much different than common stomach bugs. While physicians and hospital staff in states with legal marijuana are getting better at spotting CHS, experts note that patients in states without legalization are highly unlikely to get a correct diagnoses. Doctors unfamiliar with CHS often misdiagnose symptoms as Cyclical Vomiting Syndrome, a disease with almost identical symptoms.
