Cannabinoid hyperemesis syndrome is an uncommon reaction to cannabis use. In addition to frequent and severe vomiting, patients may have difficulty eating and drinking, and only find (temporary) relief in hot showers and baths. All the information available on AskGrowers is only for educational purposes. We do not grow, sell or promote canna products nor propagate consumption or distribution of cannabis. The data about strains, products and their effects, contained on the website is based on the consumer reviews. AskGrowers is not responsible for the accuracy of the information displayed.

This study is limited by the heterogeneity of the case series and case reports and the lack of controlled studies examining this syndrome. The alcohol rehab internal validity of our findings is limited by the possibility of missing articles from our search strategy. We limited the search to English-language articles, so any relevant articles published in foreign languages were not included, and articles not indexed in MEDLINE, Embase, Web of Science, or the Cochrane Library would be missed. Therefore, the presented diagnostic frequency is reflective only of reported criteria and low frequency may simply be a reflection of failure to report the item.
Definition of Cannabinoid hyperemesis syndrome (CHS)
- You may need to see a gastroenterologist, a doctor who specializes in the digestive tract, for a proper diagnosis.
- The only way to end CHS symptoms is to completely stop using all marijuana products.
- The pathophysiology of CHS is unclear secondary to a dearth of research dedicated to explicitly investigating its underlying mechanism.
- For each mechanism proposed, reviewers explored the supportive evidence and the study design.
- Symptoms of cannabinoid hyperemesis syndrome include frequent and debilitating bouts of vomiting sometimes accompanied by abdominal pain and weight loss.
- It’s not clear what percentage of all heavy marijuana users have experienced CHS.
Two reviewers (CS and AM) independently reviewed all titles generated by the search to identify potentially relevant articles. Articles that were clearly not relevant based on title and abstract were excluded. The full text of all relevant articles were obtained and reviewed. The define chs articles were then segregated into diagnosis, pathophysiology, or treatment categories. When the two reviewers disagreed on article eligibility, a consensus was reached through discussion.
Define core CHS data requirements:
For example, the drug affects the receptors in the esophageal sphincter, the tight band of muscle that opens and closes to let food go from your throat to your stomach. If this flap doesn’t work properly, your stomach acids might flow upward and cause you to have nausea and vomiting. One 2018 study found that 32.9% of self-reported frequent marijuana users who’d gone to the emergency room (ER) had symptoms of CHS. And a 2022 Canadian study found that ER visits for CHS-related problems had increased 13-fold between 2014 and 2021. (Recreational use and sale of cannabis in Canada was legalized starting in 2018). It’s not clear what percentage of all heavy marijuana users have experienced CHS.
The main reason for that is that the patient does not report and mention their use of cannabis. The symptoms in this phase include feeling sick and nauseous, throwing up after smoking weed, dehydration, stomach pain, disturbance of eating patterns, reduced food intake, and weight loss. Extreme vomiting and intense tummy pain can plausibly lead to scromiting (the combination of screaming and vomiting).
- By November 2024, we will develop a method of measuring waiting times in community health services at record level to provide reliable, comparable information about waits across the country.
- There is a single source of the truth about community health services from which the NHS can easily draw the timely, actionable insights we need to deliver high quality, safe, personalised care, and best outcomes for people.
- Since THC is stored in your body fat, it can take weeks to months before all the symptoms go away and you notice a difference.
- There are some drugs that may help, such as amitriptyline, Camilleri said.
- Relevant study characteristics were abstracted including study design and primary findings.
