2026 ADAI Symposium on Cannabinoid Hyperemesis Syndrome (Sept. 18): Registration & Call for Poster Abstracts Open!
06/30/2026
REGISTRATION IS OPEN for this FREE 2026 UW ADAI Symposium to learn practical, evidence-based strategies for recognizing, treating, and communicating about CHS.
The Dose Makes the Poison: Cannabinoid Hyperemesis Syndrome Goes Mainstream
September 18, 2026 | 9:00am – 4:00pm PT
Attend virtually or in person at the UW Tower Auditorium.
Cannabinoid Hyperemesis Syndrome (CHS) is becoming increasingly visible in clinical settings, but many providers are navigating diagnosis, treatment, and patient communication without clear guidance.
In a recent survey of Washington State healthcare providers, 70% reported treating patients experiencing severe abdominal pain, persistent nausea, retching, and relentless vomiting associated with heavy cannabis use.
Patients may not recognize cannabis as the cause of their symptoms, or may be skeptical that CHS exists at all, making effective care even more challenging.
Join us on September 18 to learn about:
- What we know about CHS in Washington State and the U.S.—prevalence in hospitals, emergency departments and community settings
- Recognition, diagnosis, treatment, and management across healthcare settings
- Communicating with patients about a contested diagnosis
- Policy strategies to reduce CHS and clinical strategies to increase CHS awareness and acceptance
- A research and clinical agenda for CHS
Whether you work in primary care, emergency medicine, behavioral health, nursing, pharmacy, or public health, this symposium will help you better recognize, manage, and communicate about this important cannabis-related health condition.
Certificate of attendance available for all in-person & virtual attendees; CME accreditation coming soon!
Submit an abstract for a digital poster presentation by Aug. 18
If you have any information about CHS that you want to share with others during our event, consider submitting an abstract to the 2026 ADAI Symposium describing your idea for a digital poster. Posters will be projected onscreen during the lunch break and also published on the ADAI website. Deadline: August 18, 2026.
