CHS

Cannabis Hyperemesis Syndrome

Many of our patients have called in asking about cannabinoid hyperemesis syndrome (CHS), as this syndrome has been reported in the media numerous times over the past few months. This is a very rare syndrome that occurs in long-term heavy users of THC-rich cannabis. CHS was first reported in the medical literature in 2004. Symptoms include nausea, vomiting and abdominal pain.
