The Law Changed — June 25, 2025

On June 25, 2025, the Ministry of Public Health Notification on Controlled Herbs (Cannabis) B.E. 2568 took effect. Cannabis flower is now classified as a "controlled herb." Every purchase, sale, and possession of cannabis flower requires a PT 33 (ภ.ท.33) prescription issued by one of seven licensed practitioner types. Recreational cannabis use is illegal in Thailand. Since January 2026, all dispensaries must also have a certified medical practitioner on-site during operating hours.

How to Get Medical Cannabis in Thailand

Medical cannabis in Thailand is legal but strictly prescription-only. Any product above 0.2% THC requires a PT 33 (ภ.ท.33) prescription from a licensed practitioner. Here is how to get a cannabis prescription in Thailand: visit a licensed cannabis clinic, complete a medical evaluation (350–1,500 THB depending on the clinic), and receive your PT 33 form if approved. You then take that form to a licensed dispensary to buy your medicine in person. The entire process usually takes one visit. Thai nationals, residents with a 13-digit ID, and tourists with a passport are all eligible. You must be at least 20 years old. Foreign prescriptions are not valid here.

What Is the PT 33 (ภ.ท.33) Prescription Form?

The PT 33 form (Thai: ภ.ท.33, formally "Phor Thor 33") is Thailand's mandatory prescription document for any cannabis product containing more than 0.2% THC. It has been required by law since June 25, 2025. The form is administered by the Department of Thai Traditional and Alternative Medicine (DTAM) under the Ministry of Public Health. Read our complete PT 33 prescription guide for the full step-by-step walkthrough, including what to bring and what to expect.

Every PT 33 prescription carries a unique serial number for government tracking. It specifies the exact product, strain, dosage, and treatment duration. Each form is valid for a maximum of 30 days and cannot be refilled. When it expires, you need a new consultation. The maximum possession allowed under a single prescription is 30 grams per month. All cannabis must be consumed in private settings. See our cannabis law guide for the full rules on use, transport, and storage.

1

Find a Licensed Clinic

Pick a cannabis clinic licensed by the Ministry of Public Health. Government clinics charge 350–500 THB; private clinics 800–1,500 THB. Walk-ins are accepted, but booking saves time.

2

Complete Your Medical Evaluation

A licensed practitioner reviews your medical history, current symptoms, and treatment goals. Bring your Thai ID card or passport. The evaluation typically takes 15–30 minutes.

3

Receive Your PT 33 Form

If the practitioner approves cannabis treatment, they issue a serialized PT 33 prescription specifying product type, dosage, and treatment duration. The form is valid for 30 days.

4

Buy at a Licensed Dispensary

Present your PT 33 at any licensed dispensary. Each purchase is recorded directly on the form until your 30g monthly limit is reached. Online cannabis purchases are prohibited.

7 Types of Cannabis Doctors in Thailand

Seven categories of licensed practitioners can issue PT 33 prescriptions. Each must complete DTAM-certified cannabis training before they are authorized to prescribe.

What Conditions Qualify for Cannabis in Thailand?

Thailand runs a dual-track system. The June 2025 regulation removed the original 15 conditions from the PT 33 form itself. Now each professional council publishes its own clinical guidelines. In practice, this means the type of practitioner you see determines which conditions qualify:

Practitioners in all seven categories retain clinical discretion to prescribe for conditions outside these lists based on individual patient assessment.

Who Can Get a Cannabis Prescription: Tourists, Residents, Expats

Thailand does not restrict medical cannabis to citizens. Anyone who meets the medical criteria and age requirement (20+) can receive a PT 33 prescription:

Thai Nationals

Full access with national ID card. Government clinics charge 350–500 THB for consultation. Some public hospitals provide cannabis medicine free of charge for eligible patients.

Foreign Residents

Identical access to Thai nationals. Use the 13-digit ID number from your work permit or long-term visa. Both government and private clinics are available to you.

Tourists

Can get a prescription using a passport at most private clinics. Consultation fees may be higher (800–1,500 THB). You cannot take any cannabis product out of Thailand. This is a criminal offense.

Foreign medical marijuana cards, prescriptions from other countries, and cannabis certifications from abroad have zero legal standing in Thailand. You must get a new PT 33 prescription from a Thai-licensed practitioner.

Medical Cannabis Products Available in Thailand

With a valid PT 33 prescription, you can purchase the following product types at any of Thailand's 11,136 licensed dispensaries. All transactions must happen in person. Online cannabis sales are prohibited by law:

CBD/THC Oils (Sublingual)

Popular

Placed under the tongue for absorption. Available in various CBD:THC ratios. The most commonly prescribed format and the easiest for new patients to dose accurately. Prices: 800–2,500 THB per 30ml bottle.

Dried Flower (Buds)

For smoking or vaporizing. Always requires a PT 33. Sold by the gram (300–800 THB/g). Quality and potency vary by strain and grower.

Capsules

Pre-measured doses in capsule form. Good for patients who want consistent daily dosing without taste. 500–1,500 THB for 30 capsules.

Topicals & Balms

Creams and balms applied to the skin for localized pain relief. Do not produce psychoactive effects. Popular for joint and muscle pain.

Sublingual Sprays & Tinctures

Sprayed under the tongue for fast absorption. Effects typically felt within 15–30 minutes. Good for breakthrough pain or acute nausea.

Safety, Side Effects & Precautions

Medical cannabis under proper supervision has a well-established safety profile. That said, side effects are real and dose-dependent. Start low, go slow, and report any issues to your prescribing practitioner:

Common Side Effects

Dry mouth, mild dizziness, drowsiness, red eyes, increased appetite. These affect most new users and usually fade within the first week of regular use.

Less Common Side Effects

Anxiety, paranoia, nausea, rapid heartbeat, short-term memory gaps. Almost always linked to THC doses that are too high. Lowering the dose or switching to a higher CBD ratio resolves most cases.

Drug Interactions

Cannabis affects how your liver processes certain drugs. Tell your doctor if you take blood thinners (warfarin), immunosuppressants, benzodiazepines, opioids, or antiepileptic drugs. Dosage adjustments may be needed.

Who Should Not Use Cannabis

Do not drive or operate machinery after use. Not recommended during pregnancy or breastfeeding. Patients with a history of psychosis or schizophrenia need specialist evaluation first. Minimum age: 20 years.

CBD

CBD Products (Under 0.2% THC) — No Prescription Required

Not everything requires a PT 33. CBD products that contain less than 0.2% THC are freely available at pharmacies, health stores, and retail shops across Thailand without any prescription. This includes CBD oils, capsules, topicals, and edibles. The 0.2% THC threshold is the legal dividing line: below it, you can buy over the counter; above it, you need a PT 33. See our CBD Thailand guide for product comparisons, dosage advice, and where to buy.

Thailand's Cannabis Market in 2026

Thailand had 18,433 cannabis shops before the June 2025 regulation took effect. As of early 2026, 7,297 have closed after failing to meet the stricter licensing requirements. That leaves 11,136 licensed dispensaries still operating across the country. The closures hit hardest in tourist areas where shops were selling recreationally. Since January 2026, every remaining dispensary must have a certified medical practitioner on-site during all operating hours. We verify every clinic in our directory against the government's active license database.
