Ubon Ratchathani Weed & Cannabis Shops 2026 — City Centre, Warin & PT 33 Rules

Ubon Ratchathani, on the Mun River near the Lao border, has 35 cannabis shops and two farms in our directory, drawn from public map data. Most are Thai-owned and serve local customers, so English signage is less common than in tourist towns. Some shops also sell kratom, which is covered by different rules and is not part of this guide.

How buying cannabis in Ubon Ratchathani works now

Since 26 June 2025 cannabis flower has been a “controlled herb” under the Thai Traditional Medicine Act. A shop may sell it only to someone holding a PT 33 prescription from an authorised practitioner (a doctor, a Thai traditional medicine practitioner or another prescriber certified by the Department of Thai Traditional and Alternative Medicine). The prescription is valid for up to 30 days, a licensed outlet can sell up to a 30-day supply, and since January 2026 it must keep a DTAM-trained staff member on site whenever it is open.

In our listings, Sunpasithiprasong Hospital on Sappasit Road is the clinic option. The PT 33 prescription guide explains the process. The listings on this page come from public map data, and being listed does not mean a shop is licensed. A compliant shop will ask for your prescription before it sells.
