Gastroenterology: Cannabinoid Research Clinician Packet (Nationwide Edition)

A 14-page, doctor-facing review of the cannabinoid evidence in gastroenterology, from Crohn's disease and ulcerative colitis to IBS, appetite and weight loss, with cannabinoid hyperemesis syndrome as the key caution.

Includes:

• Crohn's disease and ulcerative colitis: the Cochrane reviews and the randomized trials
• IBD in the real world: disclosure, ED visits, opioid co-use and disease outcomes
• IBS, abdominal pain and gastroparesis: what the small trials show
• Appetite and weight loss, including dronabinol's FDA-approved indication
• Key caution: cannabinoid hyperemesis syndrome (recognition, the 2026 CDC MMWR data, why stopping matters)
• Arizona in focus, older adults, and medicines to flag for pharmacist review
• A patient-conversation checklist and a 50-state + DC program table (NCSL, October 2026)
