Thai cannabis law changes often. Check the date on any page before you rely on it.

What to know locally

Local English and Thai news coverage of Rayong's cannabis shops is thin. In August 2026 Ban Khai police seized cannabis and smoking equipment and began legal action against a group of youths after a mother posted video of them smoking at her home and asked police to arrest her son.

How to get cannabis legally here

See a licensed practitioner at a clinic, or a licensed dispensary with one on site.
If appropriate, they issue a PT33 prescription, covering up to 30 days.
Buy only what is prescribed, in person, with your passport or Thai ID.
Use it in private, and keep your PT33 and receipt with you.

Clinics and dispensaries

Always confirm a shop's licence on the government's MC-GIS map before you visit. Listings are editorial and free.
