Marijuana might cause pain and vomiting in the people who value the drug the most. Doctors should learn more about cannabinoid hyperemesis syndrome.
I recently read a CBS news story about CHS, or Cannabinoid Hyperemesis Syndrome, describing a 100% increase in cases in Colorado since the legalization of marijuana there. A search for ‘THC’ and ‘CHS’ pulls stories from a range of sources including High Times, Wikipedia, Fusion.net, and Current Psychiatry. A broader search reveals articles calling the disorder ‘fake news‘.
Most articles about CHS describe the condition as rare, but becoming less rare as the legalization movement takes root and grows. The syndrome occurs in heavy, long-time users of marijuana who first notice reduced appetite, mild nausea, and sometimes weight loss. Those symptoms, and the symptoms that follow, are relieved by smoking marijuana, leading those with the condition to become heavier users who come to see marijuana as beneficial to their health.
