Cannabis in Ubon Ratchathani: clinics, dispensaries and local rules
Updated 9 November 2026
Thai cannabis law changes often. Check the date on any page before you rely on it.
What to know locally
Ubon has had a hospital medical cannabis clinic since November 2019. A December 2025 study describes doctors and licensed Thai traditional medicine practitioners there prescribing cannabis oil, mostly to cancer patients. We found few local reports about Ubon's cannabis shops since the June 2025 rules, so check any shop's licence before you go. The province borders Laos at Chong Mek: never take cannabis across.
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.
We could not confirm any listing here on the business's own website. Most details come from directories, and some shops may have closed since the June 2025 rules, so call ahead.
Clinics
Sunpasitthiprasong Hospital cannabis clinic
Sunpasit Road, Nai Mueang, Mueang Ubon Ratchathani
PT33 on site: not stated
Clinic at Ubon's main Ministry of Public Health regional hospital, named in 2019 among 12 hospitals offering cannabis consultations. The hours and phone numbers come from a 2022 guide, so call ahead to check the clinic still runs.
Det Udom Crown Prince Hospital medical cannabis clinic
Det Udom district
PT33 on site: not stated
Government hospital clinic outside the city. A 2022 study describes it prescribing DTAM cannabis oil (Deja formula), mainly to cancer patients. No address, hours or phone found, so contact the hospital first.
Dispensaries
Marsiri Gan
Ubon-Trakarn Road, Mueang Ubon Ratchathani
PT33 on site: not stated
Storefront cannabis shop in an owner-claimed directory listing last updated in April 2025, before the prescription rule, and the listing says nothing about prescriptions. Check it is still open and licensed, and bring a PT33.
Journal study (not a news report) by a Det Udom Crown Prince Hospital author on 40 patients at an Ubon tertiary hospital cannabis clinic opened in November 2019; patients, mostly with cancer, reported less pain and better appetite after about 30 days of cannabis oil prescribed by a doctor or licensed Thai traditional medicine practitioner.
