While recreational cannabis was re-criminalized in Thailand in June 2025, medical cannabis remains fully legal for those with valid prescriptions. This guide explains how foreigners - both tourists and expats - can legally access medical cannabis through proper channels.
The process requires obtaining a Thai prescription from a licensed practitioner. Foreign medical marijuana cards and prescriptions are not recognized. This guide walks you through the requirements, process, costs, and practical considerations.
Thai Prescription Requirements
To legally access medical cannabis in Thailand, individuals must obtain a PT33 prescription from a licensed Thai practitioner. This is a specific prescription form used for cannabis and controlled herb products.
| Requirement | Details |
|---|---|
| Prescription Type | PT33 form from licensed Thai practitioner |
| Minimum Age | 20 years old |
| Not Permitted | Pregnant or breastfeeding women |
| Prescription Validity | 30 days maximum |
| Supply Limit | 30-day supply per prescription |
| Consumption | Private spaces only - public use prohibited |
Who Can Issue Prescriptions?
The following licensed Thai healthcare practitioners can legally prescribe medical cannabis:
- Medical doctors (MD): Licensed physicians at hospitals and clinics
- Traditional Thai medicine practitioners: Licensed in traditional medicine (TTM)
- Chinese medicine practitioners: Licensed traditional Chinese medicine doctors
- Pharmacists: Licensed pharmacists at authorized dispensaries
- Dentists: For specific dental-related conditions
Foreign Prescriptions Are Not Valid
Your medical marijuana card from the United States, Canada, Europe, or any other country has absolutely no legal effect in Thailand. You cannot use a foreign prescription to purchase cannabis in Thailand. You must obtain a new prescription from a Thai practitioner every time.
The Medical Cannabis Access Process
Step-by-Step Process for Foreigners
Find a Licensed Clinic
Locate a clinic or hospital that serves foreigners and offers medical cannabis consultations. Major cities like Bangkok, Phuket, Chiang Mai, and Koh Samui have clinics that specialize in serving foreign patients.
Schedule a Consultation
Book an appointment with a licensed practitioner. Many clinics offer walk-in appointments, but scheduling in advance is recommended. Bring your passport and any relevant medical documentation.
Medical Evaluation
The practitioner will assess your condition, review your medical history, and determine whether medical cannabis is appropriate for your situation. Be prepared to discuss your symptoms and treatment goals.
Receive PT33 Prescription
If approved, the practitioner will issue a PT33 prescription specifying the type, dosage, and quantity of cannabis products. This prescription is valid for 30 days.
Purchase from Licensed Dispensary
Take your prescription to a licensed dispensary. Many clinics have on-site dispensaries. The dispensary will verify your prescription and provide the specified products.
Keep Documentation
Retain your prescription and purchase receipts. Keep these documents with you whenever you possess cannabis products. They are your proof of legal possession.
Qualifying Medical Conditions
Medical cannabis in Thailand is prescribed for a range of conditions. While there is no strict official list, practitioners commonly prescribe for the following:
Chronic Pain
Neuropathic pain, fibromyalgia, arthritis
Sleep Disorders
Insomnia, sleep apnea complications
Anxiety & PTSD
Anxiety disorders, post-traumatic stress
Nausea & Appetite
Chemotherapy side effects, appetite loss
Epilepsy
Seizure disorders, especially treatment-resistant
Muscle Spasticity
Multiple sclerosis, spinal cord injuries
Inflammatory Conditions
Crohn's disease, ulcerative colitis
Palliative Care
End-of-life symptom management
Practitioner Discretion
Thai practitioners have significant discretion in determining whether medical cannabis is appropriate for a patient. Being honest about your condition and treatment goals will help the practitioner make an informed decision. Some clinics are more conservative than others.
Clinics That Serve Foreigners
Several clinics in Thailand specifically cater to foreign patients seeking medical cannabis. These clinics typically offer English-speaking staff and streamlined processes for tourists and expats.
Where to Find Licensed Clinics
- Bangkok: Multiple private clinics in Sukhumvit, Silom, and hospital districts
- Phuket: Clinics in Patong, Kata, and near major tourist areas
- Chiang Mai: Clinics in the old city and Nimmanhaemin area
- Koh Samui: Clinics in Chaweng and Bophut
- Pattaya: Clinics along Beach Road and Walking Street areas
Tourist Access Uncertainty
Under the June 2025 regulations, there is conflicting information about whether short-term tourists can access medical cannabis. Some clinics continue to serve tourists; others have restricted services to long-term residents. Contact clinics directly to verify current policies before visiting.
Cost Estimates
Medical cannabis access in Thailand involves several cost components. The following estimates are based on typical 2025 pricing:
| Item | Estimated Cost (THB) | Estimated Cost (USD) |
|---|---|---|
| Initial Consultation | 500 - 2,000 THB | $14 - $57 |
| Follow-up Consultation | 300 - 1,000 THB | $9 - $29 |
| Cannabis Flower (per gram) | 200 - 800 THB | $6 - $23 |
| Cannabis Oil (10ml) | 1,000 - 3,000 THB | $29 - $86 |
| CBD Products (30ml oil) | 800 - 2,500 THB | $23 - $71 |
| Monthly Supply (typical) | 3,000 - 10,000 THB | $86 - $286 |
Prices vary significantly based on the clinic, product quality, THC/CBD ratios, and location. Bangkok clinics may charge more than those in smaller cities.
What You Can and Cannot Take Home
Critical: Export Is Absolutely Prohibited
Under no circumstances can you take cannabis products out of Thailand. This applies to all cannabis products, including CBD oils, regardless of their THC content. Attempting to leave Thailand with any cannabis product is a serious criminal offense.
What Happens at the Airport?
- Customs screening: Thai customs screens departing luggage
- Detection: Cannabis products may be detected by scans or dogs
- Consequences: Seizure, arrest, prosecution, and potential imprisonment
- No exceptions: Even small amounts of CBD oil are prohibited
At Your Destination
Even if you somehow managed to leave Thailand with cannabis (which is illegal), you would face prosecution upon arrival at your destination. Most countries have strict cannabis import laws, and many impose severe penalties including imprisonment.
Medical Cannabis ID Card
Thailand has introduced a medical cannabis patient registration system. While not required for all patients, the ID card can simplify the process for regular medical cannabis users.
- Registration through the Mor Prom app (Thai health app)
- Links your prescription history to a digital record
- May be required by some dispensaries
- Can simplify refill processes
- Primarily designed for Thai nationals but some clinics assist foreigners
Note: The ID card system is still evolving. Check with your clinic about current requirements and whether registration is necessary for your situation.
Practical Considerations
Consumption Rules
- Private only: Consume only in private spaces (your hotel room, rented accommodation)
- No public use: Parks, beaches, streets, restaurants, and bars are all prohibited
- No driving: Do not drive or operate machinery while under the influence
- Keep documentation: Always carry your prescription and receipts
Hotel Policies
- Many hotels prohibit smoking of any kind, including cannabis
- Some hotels have specific cannabis policies - check before booking
- Use of cannabis oils or edibles may be less problematic than smoking
- Respect other guests and avoid creating disturbances
Best Practices for Medical Cannabis Patients
Keep your PT33 prescription and receipts in a safe, accessible location. Consume only in private. Store products securely. Plan ahead for prescription renewals if staying more than 30 days. Contact your clinic in advance if you need to extend your prescription.
