Vomiting occurs as frequently as four or more times per hour. Nausea and vomiting in this phase are refractory to antiemetic medications. Most patients in this phase cease cannabis use because of the intensity of their symptoms.

Rates of cannabis use disorder have spiked in the past 40 to 50 years, D’Souza said, with some studies suggesting between 20 and 30 percent of marijuana users meeting the criteria for the disorder. When Dr. Deepa Camenga began her career about 20 years ago, she rarely if ever saw pediatric patients with CHS, she said. Today, hospitals in her area around New Haven, Connecticut, see pediatric CHS cases nearly every day, she added. It’s not clear if some people are more prone to the syndrome than others. However, Camilleri said that men are more likely to develop it, as are people who have used marijuana frequently and for many years. Also, it’s possible there are more cases than have been reported, since not everyone with the illness will seek medical help or tell their doctor they use cannabis, the Cleveland Clinic notes.
Why would cannabis cause the symptoms that characterize CHS?
Underdiagnosis or misclassification before broader clinical recognition of CHS was proposed as one possible explanation, alongside increased exposure and heightened diagnostic vigilance during and after the pandemic. CHS was first identified in 2004 in Australia and remains a syndrome with uncertain etiology. Proposed neurophysiological mechanisms include downregulation of cannabinoid 1 receptors, altered transient receptor potential vanilloid 1 signaling, and disrupted hypothalamic thermoregulation. It was found that, although cannabis caused increased appetite, she induced weight loss by self-induction of vomiting and excessive exercise. According to a scan of the literature in Turkey, such a case of using cannabis comorbid with anorexia nervosa has chs without vomiting not previously been reported.
Acute Symptoms of CHS
With the expanding acceptance and legalization of cannabis worldwide, healthcare providers face a crucial imperative to accurately identify CHS amidst a sea of similar clinical presentations. The purpose of this document is to provide health care professionals with key facts and recommendations for the diagnosis and treatment of patients in the emergency department. This summary was produced by Emergency Care BC (formerly the BC Emergency Medicine Network) and uses the best available knowledge at the time of publication.
While the exact cause https://ecosoberhouse.com/ is not fully understood, experts believe it may be related to how cannabinoids interact with the digestive and nervous systems over time. Cannabinoid hyperemesis syndrome (CHS), or cannabis hyperemesis syndrome, is caused by long-term cannabis (marijuana) use. People who have CHS experience repeated and severe bouts of nausea, vomiting, dehydration and stomach pain.
- Patients often use cannabis for valid medical reasons, and unsupported cessation can lead to relapse.
- People who have CHS experience repeated and severe bouts of nausea, vomiting, dehydration and stomach pain.
- Other researchers theorize that the effects of marijuana can change with chronic use.
- With the legalization of recreational cannabis in 11 states and Washington, DC, as well as medical legalization in 33 states, a record number of Americans are consuming cannabis.
Soon Facebook groups dedicated to CHS started to appear as well, with thousands of people who claimed they had these same symptoms. When first discovered in 2004, the condition was considered rare. But over the next decade, more cases of CHS started to show up in the medical literature.
Cannabinoids, the active ingredients in marijuana, bind to receptors in the intestine, and they seem to ease digestive upset. All of these words have been used to describe cannabinoid hyperemesis syndrome (CHS). Though this study can’t directly answer why CHS is becoming more common, the timing of this surge indicates that covid-19 probably played a role. At the same time, ongoing factors like the growing legalization of cannabis in the U.S. and perhaps the increased amounts of THC in today’s cannabis strains are also likely important, the researchers say.
Talk to your doctor if you believe you have cannabinoid hyperemesis syndrome. But when it does, it represents a potentially serious health condition. If you identify among those who have been using cannabis at least Alcohol Use Disorder once a day for ten years or more, you are at risk. If this use began in your early adolescence, the risk increases.
These symptoms can be severe and difficult to manage, seriously impacting someone’s quality of life and ability to function. Since these symptoms can cause dehydration, in rare uncontrolled cases it can even lead to death from kidney failure. Four in five people who have CHS recover when they stop taking marijuana products.8 If you keep using cannabis, you will continue to have problems with this syndrome for the rest of your life.
CHS typically progresses through three stages:
Haloperidol is traditionally used to treat agitation; however, it has been used successfully as an antiemetic in general surgery and oncology. D2 receptors are also present in the chemoreceptor trigger zone, which may account for these antiemetic properties. Additional studies are warranted to determine haloperidol’s place in therapy and its optimal dosing.
When should I go to the ER for cannabinoid hyperemesis syndrome?
The only way to confirm a CHS diagnosis is if symptoms are resolved after stopping cannabis use. Some people with CHS may not be diagnosed for several years or may be misdiagnosed. CHS is often confused with Cyclical Vomiting Syndrome because the symptoms experienced are similar.
The Importance of Hot Showers
If you have symptoms, your doctor will do a physical exam and ask for your detailed medical history. Let your doctor know how much marijuana you use and how often you use it. The only proven way to prevent cannabis hyperemesis syndrome is to avoid cannabis (marijuana). The only known treatment to permanently get rid of CHS is to stop cannabis use completely.
