Cannabis in Udon Thani 2026 — 52 Dispensaries, Farms & Medical Clinics

Udon Thani is one of Isan’s largest cities and a major hub for Western expats, particularly retirees with Thai partners. Situated roughly 560 km northeast of Bangkok and just 50 km from the Laos border, the city has developed a sizeable cannabis scene with 52 dispensaries, 5 farms, and 1 clinic offering PT 33 prescriptions. The total of 58 cannabis-related businesses makes Udon Thani the most active cannabis market in northeastern Thailand.

The cannabis scene here is shaped by two distinct customer bases: the established expat community that has called Udon Thani home for years, and Thai locals who make up the majority of buyers. This creates a market with both English-friendly shops in the city center and more local-oriented outlets spread across the province’s outlying districts. Prices tend to be lower than Bangkok or Chiang Mai, and several dispensaries source directly from the five local farms operating in the greater Udon Thani area.

Since the June 2025 PT 33 prescription requirement took effect, Udon Thani’s cannabis market has continued to function steadily. The city’s single listed clinic at Udon Thani Hospital handles medical cannabis consultations, though expats report that several dispensaries can assist with directing customers to a prescription source.
