In a recent survey of Washington State healthcare providers about cannabis negative effects, 70% of respondents reported seeing cases of severe abdominal pain, nausea, retching, and relentless vomiting among people reporting heavy cannabis use.
This cluster of symptoms is now recognized as Cannabinoid Hyperemesis Syndrome (CHS).
As CHS becomes more visible in clinical settings, providers are left navigating care without clear understanding or guidance. At the same time, while 1 in 10 Washingtonians who consumed cannabis in the last year report vomiting and nausea due to their cannabis use2, many people remain skeptical that the condition exists at all, creating challenges for treatment, prevention and health education.
To better understand these dynamics, we are making CHS the focus of this year’s ADAI Symposium.
Join the University of Washington’s Addictions, Drug & Alcohol Institute (home of the CTN Pacific NW Node) on September 18, 2026, to learn more about:
- CHS prevalence among adolescents and adults in U.S. emergency departments
- CHS in Washington State
- CHS as a contested disease and implications for health communication
- CHS presentation, treatment, and management across settings
- Policy recommendations to prevent CHS increase
- Improving care for individuals with CHS
