Medical Cannabis Thailand — The Complete 2026 Guide

Yes. Medical cannabis has been legal in Thailand since 2018 and remains legal under the June 2025 regulation. However, recreational use is now illegal. Any cannabis product above 0.2% THC requires a PT 33 prescription from one of seven licensed practitioner types. CBD products below 0.2% THC are available without a prescription.

Visit a licensed cannabis clinic, complete a medical evaluation (300–1,500 THB depending on the clinic), and receive a PT 33 prescription if your condition qualifies. Take the PT 33 to a licensed dispensary to purchase your medicine in person. You must be 20 or older. The whole process typically takes a single visit.

The PT 33 (ปท. 33) is Thailand's official prescription form for cannabis products containing more than 0.2% THC. Mandatory since 26 June 2025, it is issued by seven types of licensed practitioners as a paper form specifying strain, dosage, and duration, and is valid for 30 days with a commonly reported possession cap of 30 grams per month. It cannot be refilled.

Yes. Tourists can obtain a PT 33 prescription using their passport at most private cannabis clinics. Consultation fees for tourists typically run 800–1,500 THB. Foreign prescriptions and medical marijuana cards from other countries are not valid in Thailand. You cannot take any cannabis product out of the country.

Consultation fees range from 300 THB at government clinics to 1,500 THB at private clinics. Product prices: CBD/THC oil 800–2,500 THB per 30ml bottle, dried flower 300–800 THB per gram, capsules 500–1,500 THB for 30 count. Prescription renewal costs 350–500 THB every 30 days.

There is no fixed statutory condition list — each professional council issues its own clinical guidelines. Western medicine doctors typically prescribe for a narrow evidence-based set such as treatment-resistant epilepsy, chemotherapy nausea, neuropathic pain, and spasticity. Thai traditional medicine practitioners cover broader symptom categories such as chronic pain, insomnia, appetite loss, nausea, migraines, Parkinson's, and anxiety. All practitioners also have clinical discretion for other conditions.

Each PT 33 prescription is valid for a maximum of 30 days. It is single-use and cannot be refilled. After it expires, you must return to a licensed practitioner for a new evaluation and a new PT 33. Renewal consultations cost 350–500 THB.

No. All online cannabis sales have been prohibited since June 2025. Advertising cannabis on any platform is also illegal. Every purchase must happen in person at a licensed dispensary with a valid PT 33 prescription.

No. Even with a valid PT 33 prescription, cannabis must be consumed in private settings only. Public use is an offense under the Public Health Act and can result in fines. This applies to both smoking and other consumption methods.

On 26 June 2025, cannabis flower was reclassified as a controlled herb. Recreational use became illegal. All purchases now require a PT 33 prescription. Since January 2026, dispensaries must have a certified practitioner on-site. Of 18,433 shops that existed before the law, 7,297 have closed.

Both use the same PT 33 form, but they cover different conditions. Western medicine typically sticks to a narrow set of evidence-based indications. Thai traditional medicine covers broader symptom categories including chronic pain, insomnia, and anxiety. For most patients, seeing a TTM practitioner gives access to a wider range of qualifying conditions.

Possession without a PT 33 is commonly reported to carry a fine up to 25,000 THB and/or up to 3 months in prison (verify with authorities). Selling without a prescription or licence: up to 1 year imprisonment and/or a fine up to 20,000 THB under the Traditional Medicine Act B.E. 2542. Foreign nationals face deportation and permanent entry bans. Taking cannabis out of Thailand is a serious criminal offense.
