NORML, the National Organization for the Reform of Marijuana Laws, has published a Fact Sheet on CHS (Cannabis Hyperemesis Syndrome) , in the wake of reports of increasing prevelance of the condition.
Researched and written by California NORML director Dale Gieringer, the Fact Sheet says that CHS typically occurs in subjects who chronically consume large doses of THC over periods of months to several years. Subjects typically begin by experiencing episodic nausea, vomiting, and abdominal pain, which they often attempt to treat by using more cannabis. However, the only way of stopping CHS attacks is to completely abstain from cannabis.
CHS is easily confused with a similar disorder, cyclic vomiting syndrome (CVS), which is also characterized by nausea, vomiting and abdominal pain, but it is not caused by prior cannabis use. Many patients use cannabis to treat CVS, making it difficult to distinguish from CHS. Patients experiencing these symptoms should consult a physician, and the continuation of symptoms after cessation of cannabis use could be indicative of a medical condition other than CHS.
The bottom line for consumers: avoid chronic, intensive use of THC-rich cannabis, such as dabs, infused pre-rolls, and hashish or vape concentrates. If you experience episodic attacks of nausea, vomiting and intestinal cramps, try abstaining from cannabis rather than escalating your consumption.
The University of California at Irvine is conducting a survey about CHS. Interested patients are invited to apply.
Founded in 1972, Cal NORML advocates for the rights and well being of cannabis users in California. We were the first to publish studies on cannabis vaporization, and regularly put out health warnings for our members and supporters.
