What is Cannabinoid Hyperemesis Syndrome?
Often mistakenly called Cyclical Vomiting Syndrome, Cannabinoid Hyperemesis Syndrome is a rare form of cannabinoid toxicity that develops in chronic smokers. It’s characterized by cyclic episodes of debilitating nausea and vomiting. People who suffer from the syndrome often find that hot showers relieve their symptoms, and will compulsively bathe during episodes of nausea and vomiting. Symptoms stop after cessation of cannabis use.
Cyclic Vomiting Syndrome is different from Cannabinoid Hyperemesis Syndrome—though the symptoms are very similar. Cyclic Vomiting Syndrome is not caused by cannabis consumption.
This may sound scary, but it’s very rare. I’ve known many heavy smokers all my life and have only recently heard of it through research online. People are blaming the recent and increasing popularity of dabs for Cannabinoid Hyperemesis Syndrome (CHS), but CHS has been around since way before concentrates were popular. An Australian clinical study from 2004 looked into the syndrome in a group of 10 patients suffering from CHS, and all were marijuana smokers, not dabbers.
