What to know locally
When the medical-only rules took effect in June 2025, Chiang Mai's Provincial Public Health Office said it oversaw about 823 licensed cannabis businesses across 22 districts, more than 300 of them in Mueang district, and promised random inspections with licence suspension or revocation for violators. By November 2026 the national government counted 482 licensed cannabis outlets in Chiang Mai, the fifth-highest of any province, and said repeat offenders nationwide now face immediate licence revocation.
