Awareness of Cannabinoid Hyperemesis Syndrome (CHS) is gradually spreading throughout the medical community, however it seems to me that there is still a massive lack of awareness amongst cannabis users generally. There is also much scepticism and hostility directed at the idea that cannabis could cause such an illness. This is understandable given that news of CHS as a condition only reached the medical literature in late 2004.1
I'm not anti-cannabis, in fact I'm very pro-cannabis and anti-prohibitionist in regards to all drugs; I believe in personal liberty. My concern is that there are doubtless many sufferers of this condition who do not known that cannabis is causing their illness. CHS has hospitalised many people, who have subsequently required intravenous fluids to rehydrate their bodies. The vomiting caused by this condition is of such severity that during their episodes of hyperemesis, sufferers can scarcely keep any fluids down, which leads to serious dehydration. It is surprising that to date there are no known fatalities attributed to CHS, in my opinion, this is a very real prospect - especially considering the rising popularity of high THC concentrated forms of cannabis.
I believe we can do more, as a harm reduction forum, to spread awareness of CHS. Please educate yourselves on the symptoms of CHS and look out for friends, family members and all cannabis users.
Symptoms of CHS include:
CHS tends to occur in people who:
It's probable that CHS is much more prevalent than most people know. Many individuals have likely been misdiagnosed as cyclical vomiting syndrome (CVS), which shares some essential features. But many more still, are likely to be undiagnosed and suffering. Unfortunately many sufferers will continue to smoke to relieve the nausea, which unbeknown to them, is actually being caused by their use of cannabis.

Symptoms of CHS include:
- Loss of appetite in the prodrome phase, which leads up to bouts of morning sickness
- abdominal pain
- extremely frequent vomiting in the hyperemesis phase, which can last for days
- feeling very thirsty
- becoming mostly relieved of the symptoms in a hot shower, which can lead to compulsive frequent showering behaviours
- cyclic pattern of the described symptoms over months
CHS tends to occur in people who:
- Have smoked cannabis heavily and daily for many years
