The American Gastroenterological Association issued its first clinical practice update on cannabinoid hyperemesis syndrome, providing expert-reviewed guidance on diagnosis and management of this increasingly common condition.
Gastroenterologists, emergency physicians, primary care doctors, cannabis-using patients with GI symptoms
First AGA clinical practice update on CHS
What the researchers found
The AGA Clinical Practice Update provides consensus expert guidance on recognizing, diagnosing, and treating CHS, a condition characterized by cyclic nausea, vomiting, and compulsive hot water bathing in the setting of chronic cannabis use. The update underwent internal and external peer review.
Why it matters
CHS is increasingly common with rising cannabis use but remains underdiagnosed. Having the AGA, the leading US gastroenterology organization, publish formal guidance legitimizes the condition and gives clinicians a reference standard for diagnosis and management.
The numbers in context
First AGA clinical practice update on CHS; peer-reviewed by CPUC and approved by AGA Governing Board.
How the study worked
Expert commentary commissioned by the AGA Clinical Practice Updates Committee, incorporating published evidence and author experience, with internal and external peer review.
What this study cannot tell us
Expert commentary rather than systematic review. Based on limited published evidence. Author experience may not represent all clinical settings.
How to read the evidence
AGA-commissioned expert commentary with peer review, representing professional consensus rather than systematic evidence review.
When this study was published
2024 publication
The bigger picture
As cannabis use increases, emergency departments and gastroenterologists are seeing more CHS cases. Official professional society guidance helps standardize care and may reduce the diagnostic delays that characterize this condition.
Questions still open
- Will this guidance reduce the average time to CHS diagnosis?
- Are the recommended treatments supported by randomized controlled trials?
Common questions
What is cannabinoid hyperemesis syndrome?
How is CHS diagnosed and treated?
