Thai cannabis law changes often. Check the date on any page before you rely on it.
Chiang Rai had only about 20 cannabis dispensaries when the prescription rule arrived in June 2025, clustered near the Night Bazaar and the Kok River, and some owners said most of their trade was tourists without local doctors. In August 2025 the governor's "Chiang Rai Fa Sai" operation arrested the manager of a licensed shop behind Chiang Rai Prachanukroh Hospital for selling flower and kratom drinks to students without checking prescriptions or ages, and provincial health officials said they would review licences and spot-check similar shops.
Always confirm a shop's licence on the government's MC-GIS map before you visit. Listings are editorial and free.
