How to Choose a Cannabis Clinic in Thailand: Complete Guide

Since Thailand transitioned to a medical cannabis framework in mid-2025, visiting a licensed cannabis clinic is now the only legal way to obtain cannabis flower and most THC-containing products. With thousands of clinics operating across the country — ranging from government hospital departments to private wellness clinics — choosing the right one can feel overwhelming.

The clinic you visit matters. A good clinic will take time to understand your health situation, issue a proper PT 33 prescription, recommend appropriate products and dosages, and provide ongoing support. A poor clinic may rush you through a meaningless consultation, pressure you into expensive purchases, or worse, operate without proper licensing.

This guide gives you the tools to evaluate any cannabis clinic in Thailand so you can make an informed choice. We do not recommend specific clinics or businesses — instead, we explain what to look for, what to avoid, and how to get the best possible care.

Understanding the Current Landscape

Thailand’s cannabis market has changed dramatically since the June 2025 regulations took effect. The open recreational market that existed from 2022 to 2025 has been replaced by a medical framework requiring practitioner oversight and PT 33 prescriptions for all cannabis flower purchases.

Of the roughly 18,400 cannabis shops that operated at the market’s peak, around 40% have closed because they could not meet the new requirements — primarily the mandate to have a licensed practitioner on-site during all operating hours. The approximately 11,000 that remain operate as medical cannabis clinics or dispensaries with attached clinical services.

This shakeout has generally been positive for consumers. The shops that survived tend to be more professional, better stocked, and staffed by qualified practitioners. However, quality still varies significantly, and it is worth doing your homework before choosing a clinic.

Types of Cannabis Clinics in Thailand

Not all cannabis clinics operate the same way. Understanding the different types will help you find the best fit for your needs, budget, and language preferences.

1. Government Hospital Cannabis Clinics

Many public hospitals across Thailand now operate dedicated cannabis medicine departments or clinics. These were among the first legitimate cannabis providers in the country, beginning in 2019 when medical cannabis was initially legalized for limited use.

What to expect:

• Staffed by licensed physicians and pharmacists employed by the Ministry of Public Health
• Access to government-produced cannabis products, often at subsidized prices
• Thorough medical intake and documentation process
• Integration with your broader medical records if you are already a patient at the hospital
• Longer wait times, especially at popular locations
• Primarily Thai-language service, though some hospitals in Bangkok and tourist areas have English-speaking staff

Best for: Thai residents with a specific medical condition seeking affordable, well-documented care. Patients who want their cannabis treatment integrated with other medical care they receive at the same hospital.

Considerations: The process tends to be more bureaucratic. You will likely need to register as a hospital patient, wait in a queue, and the product selection may be limited to government-manufactured cannabis products. Appointments may need to be booked in advance, and walk-in availability varies by location. English-language support is not guaranteed.

2. Private Medical Clinics

Private clinics offering cannabis consultations have become widespread since the 2025 regulatory changes. These range from dedicated cannabis medicine practices to general medical clinics that have added cannabis services.

What to expect:

• Shorter wait times and appointment availability
• English-speaking staff common in tourist and expatriate areas
• Broader product selection from multiple licensed producers
• Higher consultation fees than government hospitals
• More comfortable waiting areas and patient experience
• Practitioner may be a physician, traditional medicine practitioner, or pharmacist

Best for: Expats, tourists, and anyone who values convenience, English-language service, and a wider product selection. Also suitable for those who want more time with the practitioner to discuss their situation.

Considerations: Quality varies widely. Some private clinics are excellent medical practices with knowledgeable staff. Others are essentially shops that added a practitioner to comply with regulations without genuinely embracing the medical consultation process. The higher cost does not automatically guarantee better care — evaluate each clinic on its merits.

3. Traditional Thai Medicine (TTM) Clinics

Traditional Thai Medicine practitioners (known as “mor phaen Thai”) represent the largest group of cannabis prescribers in Thailand. TTM has a centuries-long history of using cannabis in herbal formulations, and when cannabis was re-legalized, TTM practitioners were among the first authorized to prescribe it.

What to expect:

• A holistic assessment that considers your overall constitution, not just a single symptom
• Cannabis recommendations that may include traditional formulations — oils, balms, compresses, and herbal blends combining cannabis with other Thai medicinal herbs
• Practitioners who view cannabis as one tool within a broader traditional medicine framework
• Strong emphasis on proper dosage and gradual adjustment
• Prices generally in the low to mid-range
• Sessions may include brief education about traditional Thai approaches to wellness

Best for: Patients open to a holistic approach. Those interested in cannabis as part of a broader wellness protocol rather than a standalone treatment. Patients looking for topical preparations, herbal formulations, and traditional cannabis medicines.

Considerations: The philosophical approach differs from Western medicine. If you prefer a purely evidence-based, clinical approach, a TTM clinic may not be the right fit. Language can be a barrier, as many TTM practitioners work primarily in Thai. Product selection may lean toward traditional preparations rather than modern cannabis products like vaporizer cartridges or precisely dosed edibles.

4. Telemedicine and Online Clinics

A growing number of licensed clinics now offer consultations via video call, phone, or messaging apps. This is a relatively new development that gained momentum after the 2025 regulations required prescriptions for all cannabis purchases.

What to expect:

• Consultation from your home, hotel, or wherever you have internet access
• Digital issuance of the PT 33 prescription, which can be presented at licensed dispensaries
• Often available outside standard business hours, including evenings and weekends
• Typically staffed by licensed practitioners who also work at physical clinics
• Lower overhead may translate to slightly lower consultation fees
• Follow-up appointments and prescription renewals are particularly convenient via telemedicine

Best for: Patients in rural areas without nearby clinics. People with mobility limitations. Those seeking prescription renewals who have already established a relationship with a practitioner. Tourists who want to obtain a prescription before arriving at a dispensary.

Considerations: Telemedicine has limitations. The practitioner cannot physically examine you, which may be relevant for certain conditions. Some dispensaries may be less familiar with digital PT 33 forms, though this is becoming less common as the system matures. Verify that the telemedicine provider is properly licensed in Thailand — the practitioner must hold Thai credentials regardless of where they are physically located during the call.

5. Dispensary-Attached Clinics

Many licensed dispensaries have an on-site practitioner who conducts consultations in the same location where products are sold. This is the most common model in Thailand, especially outside major cities.

What to expect:

• Consultation and product purchase in a single visit
• The practitioner can show you specific products and explain their characteristics
• Convenience — no need to obtain a prescription at one location and fill it at another
• Wait times depend on how busy the dispensary is
• Product recommendations may be influenced by what the dispensary has in stock
• Some dispensaries include the consultation fee in the product price

Best for: Convenience-oriented patients. First-time visitors who want guidance on product selection. Tourists who want to complete the entire process in one stop.

Considerations: This model creates an inherent potential conflict of interest — the clinic’s revenue is tied to product sales. A reputable dispensary-attached clinic will still conduct a genuine consultation and recommend what is best for you, even if that means suggesting a lower-cost product or fewer items than you expected. Be wary of clinics where the “consultation” feels like a sales pitch rather than a medical assessment.

Who Can Prescribe Cannabis in Thailand

Under current Thai regulations, seven categories of licensed healthcare practitioners can prescribe cannabis and issue PT 33 forms, provided they have completed approved cannabis medicine training. Understanding who these practitioners are helps you evaluate whether a clinic is operating legitimately.

The Seven Authorized Practitioner Types

1. Medical Doctors (Physicians)

Licensed physicians registered with the Medical Council of Thailand can prescribe cannabis after completing the Department of Thai Traditional and Alternative Medicine (DTAM) approved cannabis training course. They approach cannabis from a Western medical perspective and are most likely to be found in government hospitals and private medical clinics.

2. Traditional Thai Medicine Practitioners

Licensed TTM practitioners registered with the Thai Traditional Medicine Professions Council form the largest group of cannabis prescribers. Their training in cannabis goes back to traditional Thai pharmacopoeia, and many have extensive experience with cannabis-based herbal formulations. They must hold an active TTM license and have completed additional cannabis certification.

3. Traditional Chinese Medicine Doctors

Practitioners of Traditional Chinese Medicine (TCM) who are licensed in Thailand can also prescribe cannabis. TCM practitioners bring their own diagnostic framework and may integrate cannabis into traditional Chinese herbal treatment plans. They are less common than TTM practitioners but can be found in areas with significant Chinese-Thai communities.

4. Pharmacists

Licensed pharmacists registered with the Pharmacy Council of Thailand can prescribe cannabis after completing approved training. Pharmacists are particularly knowledgeable about drug interactions, dosing, and product formulation. In some dispensary models, the pharmacist serves as both the prescriber and the product expert — a useful combination.

5. Dentists

Licensed dentists can prescribe cannabis for conditions within their scope of practice, such as chronic jaw pain, TMJ disorders, or post-surgical pain management. This is a less common scenario, but it is legally permitted.

6. Approved Nurses

Certain nurse practitioners who have completed cannabis medicine certification can prescribe cannabis under specific circumstances. This is typically limited to nurses working in clinical settings under the supervision or protocol of a physician or TTM practitioner.

7. Veterinarians

Licensed veterinarians can prescribe cannabis for animal patients. This is relevant if you are seeking cannabis treatment for a pet. The veterinarian must have completed cannabis training and will issue a PT 33 appropriate for veterinary use.

Verifying Practitioner Credentials

Every practitioner who prescribes cannabis should be able to provide proof of their:

• Professional license number (from their respective council)
• Cannabis medicine certification (from a DTAM-approved training program)
• Current registration status

You do not need to ask to see these documents at every visit, but a legitimate practitioner will not hesitate if you do ask. Their license information should also appear on your PT 33 form. For more details about the PT 33 process, see our comprehensive PT 33 prescription guide.

What Makes a Good Cannabis Clinic

Beyond the basic categories above, certain qualities distinguish an excellent cannabis clinic from a mediocre one. Here is what to look for.

Proper Credentials and Licensing

A legitimate clinic will:

• Display its Thai FDA cannabis license prominently at the premises
• Have at least one licensed practitioner on-site during all operating hours
• Be willing to show you the practitioner’s credentials if asked
• Operate from a registered business address (not a temporary market stall or pop-up)

Thorough Consultation Process

The consultation is the core of a cannabis clinic visit. A good consultation includes:

Medical history review. The practitioner should ask about your current health conditions, medications, allergies, and what you are hoping to achieve with cannabis. This should not be a checkbox exercise — they should genuinely listen and ask follow-up questions.

Assessment of suitability. Not everyone is a candidate for every cannabis product. A responsible practitioner will consider contraindications, potential drug interactions, and whether cannabis is actually the best option for your situation. They should be willing to say “this may not be right for you” when appropriate.

Education and expectation setting. A good practitioner will explain how cannabis works, set realistic expectations about outcomes, discuss potential side effects, and explain how to use the products properly. If you have never used cannabis before, this education component is particularly important.

Dosage guidance. “Start low and go slow” is the standard mantra in cannabis medicine, but a good practitioner will give you specific guidance — starting dose, how to adjust, what to look for, and when to follow up.

Proper PT 33 documentation. Every cannabis prescription must be documented on the official PT 33 form, which includes patient information, practitioner information, the prescribed cannabis products, quantities, and dosing instructions. The form becomes your legal authorization to possess the cannabis products.

Product Knowledge

The practitioner and staff should be knowledgeable about:

• Different cannabis strains and their typical effects
• The difference between THC-dominant, CBD-dominant, and balanced products
• Various consumption methods (smoking, vaporizing, oils, edibles, topicals) and their advantages and disadvantages
• How different products might address different conditions or symptoms
• Onset times and duration of effects for different consumption methods

If the staff cannot answer basic questions about their products beyond reading the label, that is a concern.

Follow-Up Care

Cannabis treatment is not a one-time transaction. A good clinic will:

• Schedule or recommend a follow-up appointment (typically 2-4 weeks after the initial visit)
• Provide a way to contact them with questions between appointments
• Adjust your treatment plan based on your experience and feedback
• Keep records of your treatment history so they can track what has worked and what has not

No Pressure Selling

Perhaps the most important quality: a good clinic does not pressure you to buy. The consultation should feel like a medical appointment, not a sales pitch. Signs of a no-pressure environment include:

• The practitioner recommends a specific product and dosage, rather than suggesting you “try everything”
• Starting recommendations are modest rather than pushing the largest or most expensive option
• You feel comfortable saying “I would like to think about it” without being pressured
• The practitioner recommends CBD products (which do not require a prescription) when they are more appropriate than THC products

Red Flags: What to Avoid

Knowing what to avoid is just as important as knowing what to look for. These warning signs suggest a clinic may not be operating properly or has your best interests at heart.

No Consultation Before Selling

If a shop hands you cannabis products without any meaningful consultation — no questions about your health, no assessment, no discussion of dosage — it is not operating as a legitimate clinic. The June 2025 regulations require a genuine medical consultation before a PT 33 can be issued. A 30-second exchange of “what do you want?” does not constitute a consultation.

No PT 33 Prescription Form

Every legal cannabis purchase must be accompanied by a PT 33 prescription. If a shop sells you cannabis flower or THC products without providing a PT 33 form, both you and the shop are violating current regulations. You should receive a copy of the PT 33 for your records — it is your legal proof of authorized possession.

Learn exactly what a PT 33 looks like and what it should contain in our PT 33 prescription guide.

Unverified Practitioners

Be cautious if:

• There is no practitioner visibly present during your visit
• The “practitioner” cannot provide a license number or credentials
• The same person who serves as the budtender also claims to be the prescriber without visible credentials
• The PT 33 form appears to be pre-signed or photocopied rather than individually issued

Making Cure Claims

Cannabis can be helpful for many conditions, but it is not a miracle cure. Be wary of any clinic or practitioner that:

• Guarantees cannabis will cure a specific disease
• Claims cannabis can replace all your current medications
• Dismisses the value of conventional medical treatment
• Makes claims that sound too good to be true

Responsible practitioners discuss cannabis in terms of symptom management, quality of life improvement, and complementary care — not guaranteed cures.

Selling Without Records

A legitimate clinic maintains patient records. If the clinic does not take your name, does not record your medical history, and does not keep any documentation of the consultation, it is not operating as a proper medical facility. These records are required by regulation and are also important for your continuity of care.

Unusually High Prices Without Justification

While private clinics are entitled to charge market rates, be cautious of prices that are dramatically higher than average without clear justification. Some clinics in tourist areas charge premium prices simply because they can. Compare prices across multiple clinics before committing to a purchase, especially for large quantities.

Unsanitary or Unprofessional Environment

Cannabis is a medical product, and the premises where it is dispensed should reflect that. Concerns include:

• Products stored improperly (exposed to direct sunlight, extreme heat, or humidity)
• No visible hygiene practices when handling products
• A general atmosphere that feels more like a party venue than a healthcare setting
• Staff who are visibly impaired while working

Cost Comparison by Clinic Type

Understanding typical costs helps you budget and identify potential overcharging. The following table reflects typical ranges as of early 2026. Prices vary by location, with Bangkok and tourist areas generally on the higher end.

Important notes on pricing:

• Some clinics include the consultation fee in the price of the first product purchase, so the consultation is effectively “free” if you buy something
• Government hospital prices are generally the lowest but may involve longer wait times and limited product selection
• Product prices (cannabis flower, oils, edibles) vary based on strain, potency, producer, and quantity — this is separate from the consultation fee
• Follow-up consultations are often cheaper than initial visits, sometimes 50-75% less

What to Expect at Your First Visit

Knowing what happens at a cannabis clinic visit helps you prepare and also helps you evaluate whether the clinic is following proper procedures.

Step 1: Registration

When you arrive, you will be asked to register as a patient. This typically involves:

• Presenting a valid ID (passport for foreigners, Thai national ID for residents)
• Filling out a patient registration form with your personal details
• Providing contact information
• At government hospitals, you may need to complete the hospital’s general registration process first

Step 2: Medical History and Intake

Before seeing the practitioner, you may be asked to complete a health questionnaire covering:

• Current medical conditions
• Current medications and supplements
• Previous experience with cannabis (if any)
• Allergies
• The primary reason you are seeking cannabis treatment
• Your goals and expectations

Some clinics handle this through a paper form, others through a digital intake process, and some through a direct conversation with the practitioner.

Step 3: Practitioner Consultation

This is the most important part of the visit. The practitioner will:

• Review your medical history and intake information
• Ask additional questions about your condition and symptoms
• Discuss your experience with cannabis (if any)
• Assess whether cannabis is appropriate for your situation
• Explain available product options and their differences
• Recommend specific products, strains, and dosages
• Discuss potential side effects and drug interactions
• Explain proper usage and storage
• Set expectations for outcomes and timeline

A thorough initial consultation typically takes 15-30 minutes. If it lasts less than 5 minutes, the clinic is likely rushing through the process to maximize throughput.

Step 4: PT 33 Prescription

If the practitioner determines cannabis is appropriate, they will issue a PT 33 prescription. This is the official document that authorizes you to purchase and possess the specified cannabis products. The form includes:

• Your personal information
• The practitioner’s license information
• Specific products prescribed (strain, form, quantity)
• Dosage instructions
• Date of issue

You should receive a copy of this form. Keep it with you whenever you are in possession of cannabis products — it is your legal authorization.

Step 5: Product Selection and Purchase

If the clinic has an attached dispensary (most do), you can purchase your prescribed products immediately. The staff should:

• Show you the products that match your prescription
• Explain how to use them properly
• Provide any relevant storage instructions
• Package products appropriately
• Provide a receipt

If the clinic does not sell products on-site, your PT 33 prescription can be presented at any licensed dispensary. You can browse our clinic and dispensary directory to find licensed locations near you.

Step 6: Follow-Up Scheduling

Before you leave, the clinic should discuss follow-up care:

• When to schedule a follow-up appointment (typically 2-4 weeks)
• How to reach the clinic if you have questions or concerns
• What to do if you experience unwanted side effects
• When your prescription will need renewal

Choosing a Clinic by City

While we do not recommend specific clinics, here are general observations about the cannabis clinic landscape in Thailand’s major cities and tourist destinations.

Bangkok

As the capital and largest city, Bangkok has the highest concentration of cannabis clinics of all types — government hospitals with cannabis departments, private medical clinics, TTM clinics, and dispensary-attached clinics. The greatest selection of English-speaking clinics is found here, particularly in areas like Sukhumvit, Silom, Khao San, and Asoke. Competition keeps prices reasonable, though tourist-centric areas may charge premium rates. Telemedicine options are also most developed among Bangkok-based providers.

Chiang Mai

Chiang Mai has a strong cannabis clinic scene, partly driven by its large expat community and wellness tourism sector. The city has notable strength in Traditional Thai Medicine clinics, reflecting northern Thailand’s deep herbal medicine traditions. English-speaking clinics are available, particularly in the old city and Nimmanhaemin areas. Prices tend to be slightly lower than Bangkok.

Phuket

Phuket’s clinics are heavily oriented toward tourists, with widespread English-language availability and many clinics in Patong, Kata, and Phuket Town. Expect tourist-area pricing, which may be higher than the national average. The upside is convenience — many Phuket clinics are accustomed to serving international visitors and have streamlined the process for first-time patients.

Pattaya

Pattaya has a high density of dispensary-attached clinics, particularly along Walking Street, Beach Road, and Second Road. The scene is heavily tourist-oriented. Quality varies significantly — take extra care to evaluate clinics in Pattaya, as the fast-turnover tourist market can attract operators who prioritize volume over quality care. That said, reputable clinics absolutely exist in Pattaya; you just need to do your due diligence.

Koh Samui

Koh Samui’s cannabis clinic scene is smaller but growing, serving both tourists and the island’s expat community. Clinics are concentrated in Chaweng, Lamai, and Nathon. The smaller market means fewer options, but the clinics that have survived the regulatory transition tend to be well-established. English-language service is common. Prices are comparable to Phuket.

Other Locations

Cannabis clinics exist throughout Thailand, including in smaller cities and rural areas. Outside major tourist destinations, clinics are more likely to operate primarily in Thai, and the selection of products may be more limited. Government hospitals with cannabis departments provide a reliable option in most provinces.

For Tourists vs. Residents: Different Priorities

Your priorities when choosing a clinic may differ depending on whether you are a tourist or a long-term resident.

If You Are a Tourist

Priority: Convenience, language, and speed.

As a visitor, you likely want a clinic that:

• Has English-speaking (or your language) practitioners and staff
• Accepts walk-in patients or can see you on short notice
• Handles the entire process (consultation, prescription, product purchase) in one location
• Is located near your accommodation or tourist areas
• Can complete the process in a single visit

You do not need a Thai medical history or referral. A valid passport is sufficient for identification. The process can typically be completed in 30-60 minutes for a first visit.

For a complete overview of cannabis rules for visitors, see our guide for tourists.

Tips for tourist clinic visits:

• Call ahead or check online to confirm the clinic is open and a practitioner is available — some clinics have limited practitioner hours
• Ask about language availability before visiting
• Bring your passport — it is required for the PT 33 form
• If you are visiting multiple Thai cities, ask whether your PT 33 prescription will be accepted at dispensaries in other locations (it should be, as it is a national form)
• Keep your PT 33 form safe — you need it to legally possess the products

If You Are a Resident

Priority: Ongoing relationship, treatment continuity, and value.

As a long-term resident, you have the luxury of building a relationship with a practitioner over time. Look for a clinic that:

• Is conveniently located for regular visits
• Maintains detailed patient records
• Has a practitioner you trust and feel comfortable with
• Offers competitive pricing for ongoing treatment
• Provides easy prescription renewals
• Has a follow-up care protocol
• Is willing to coordinate with your other healthcare providers if relevant

Residents may benefit from trying a government hospital cannabis clinic first. The prices are the lowest, and the level of medical documentation tends to be thorough. If the language barrier or wait times are problematic, a private clinic with a good practitioner is a worthwhile investment for ongoing care.

Tips for resident clinic visits:

• Ask about loyalty programs or package pricing for ongoing treatment
• Request that the clinic maintain a complete treatment history
• Consider telemedicine for routine prescription renewals after the initial in-person visit
• If you find a good practitioner, stick with them — continuity of care leads to better outcomes
• Keep copies of all your PT 33 forms for your personal records

The Follow-Up and Renewal Process

Cannabis treatment is not a one-time event. Here is how the ongoing relationship with your clinic should work.

Initial Follow-Up (2-4 Weeks)

After your first visit, a follow-up appointment allows the practitioner to:

• Assess how you responded to the initial product and dosage
• Address any side effects or concerns
• Adjust the dosage up or down based on your experience
• Consider alternative products if the initial recommendation was not effective
• Answer questions that have come up since your first visit

This follow-up is particularly important for first-time cannabis users. Even experienced users benefit from a check-in, as medical-grade products may differ from what they have used previously.

Prescription Renewals

PT 33 prescriptions have a defined validity period. When your prescription approaches expiration, you will need a renewal consultation. This is typically shorter and less expensive than the initial visit, as the practitioner already knows your history and treatment plan.

Many clinics allow renewals via telemedicine, which is convenient for stable patients who do not need dosage adjustments. Some clinics offer automatic renewal reminders via messaging apps or email.

Adjusting Your Treatment Plan

Over time, your needs may change. A good clinic adapts:

• If your condition improves, the practitioner may recommend reducing dosage or frequency
• If results plateau, they may suggest trying a different strain, consumption method, or product type
• If new symptoms or conditions arise, the treatment plan should be re-evaluated
• Seasonal changes, lifestyle shifts, and other medications may all affect your cannabis treatment

When to Switch Clinics

Sometimes a clinic is not the right fit. Consider switching if:

• The practitioner does not listen to your concerns or feedback
• You feel pressured to buy more than you need
• The clinic does not maintain proper records of your treatment history
• Follow-up care is nonexistent or perfunctory
• You consistently feel rushed during appointments
• Pricing seems unreasonable compared to alternatives

When switching, ask your current clinic for a copy of your treatment records. A new clinic will be able to provide better care with a complete history of what you have already tried.

10 Questions to Ask Your Cannabis Practitioner

Asking the right questions helps you evaluate the clinic and ensures you get the most out of your consultation. Here are ten questions worth asking.

1. “What is your training and experience with cannabis medicine?”

A legitimate practitioner will be happy to share their credentials, including their professional license type and the cannabis training program they completed. This question also helps you gauge their depth of experience — someone who has been prescribing cannabis for several years will likely have a broader understanding than someone who just completed their certification.

2. “Why are you recommending this specific product for my situation?”

The answer should reference your specific symptoms, medical history, and goals — not just “this is our most popular product” or “this is our best seller.” A thoughtful answer demonstrates that the practitioner is making an individualized recommendation.

3. “What dosage should I start with, and how should I adjust?”

Expect specific guidance, not vague suggestions. A good answer includes a starting dose in milligrams or a specific measurement (e.g., “start with one small inhalation” or “take 0.25ml of oil”), a timeline for adjustment, and clear instructions on how to increase if needed.

4. “Are there any interactions with my current medications?”

If you are taking other medications, this is a critical question. Cannabis can interact with certain drugs, including blood thinners, anti-seizure medications, and some antidepressants. A practitioner who dismisses this question or does not ask about your other medications is a concern.

5. “What side effects should I watch for?”

Common side effects of cannabis include dry mouth, drowsiness, dizziness, changes in appetite, and temporary anxiety (especially with higher THC doses). A responsible practitioner will proactively discuss these rather than pretending they do not exist.

6. “How long should I expect before I notice benefits?”

The timeline varies by condition, product type, and individual. Inhalation provides near-immediate effects, while oils and edibles may take 1-2 hours. For chronic conditions, therapeutic benefits may build over days or weeks of consistent use. The practitioner should give you realistic expectations.

7. “What is the difference between the products you carry?”

This question tests the staff’s product knowledge. They should be able to explain differences in strain, cannabinoid profile, terpene content, consumption method, onset time, and duration. If the answer is limited to “this one is stronger,” the clinic may lack adequate expertise.

8. “What happens if this product does not work for me?”

A good clinic has a plan for when the first recommendation is not effective. The answer should involve a follow-up visit, trying a different product or dosage, and possibly exploring a different consumption method. Avoid clinics that treat each visit as a standalone transaction with no continuity.

9. “How do I schedule a follow-up or reach you with questions?”

This question reveals whether the clinic has a genuine follow-up care system. Ideally, they will offer multiple contact methods (phone, messaging app, email) and clear guidance on when to follow up.

10. “Can you explain my PT 33 form?”

Ask the practitioner to walk you through your PT 33 prescription. They should be able to explain every section — your information, their information, the products prescribed, the dosage instructions, and the validity period. This also confirms they are actually issuing a real PT 33 rather than a generic form or receipt.

How to Verify a Clinic’s Legitimacy

Beyond asking questions during your visit, there are steps you can take before and after to confirm a clinic is operating legally and properly.

Before Your Visit

Check for an online presence. While not all legitimate clinics have websites, a complete lack of online presence (no website, no Google Business listing, no social media) may be a concern for a business that has supposedly been operating for some time. Reviews from other patients can provide valuable insight.

Look for licensing information. Some clinics display their FDA license number on their website or social media. If available, you can cross-reference this with Thai FDA records.

Ask about the practitioner. When calling or messaging to book, ask who the practitioner is and what type of license they hold. A legitimate clinic will answer this openly.

Consult directories. Licensed clinic directories, including the one we maintain in our clinic directory, can help verify that a clinic is recognized and operating under proper authority.

During Your Visit

Look for the license. The clinic’s FDA cannabis license should be displayed at the premises, typically in a frame near the reception or consultation area.

Verify the PT 33. When you receive your prescription, check that it is an official PT 33 form — not a handwritten note, a generic receipt, or a photocopy. It should include the practitioner’s name, license number, and signature.

Assess the consultation. Did the practitioner ask about your medical history? Did they explain the product and dosage? Did they discuss potential side effects? A genuine medical consultation covers these points.

Check product packaging. Legitimate cannabis products sold through licensed dispensaries should have proper labeling, including the producer’s name, cannabinoid content (THC and CBD percentages), batch number, and Thai FDA registration.

After Your Visit

Verify your PT 33 details. Check that your name, the date, the products, and the practitioner’s information are all correct on your PT 33 form. Errors could cause problems if you are asked to present it.

Keep records. Save your PT 33 forms, receipts, and any documentation the clinic provides. These are important for continuity of care and legal protection.

Report concerns. If you believe a clinic is operating without proper licensing, selling cannabis without prescriptions, or engaging in other violations, you can report concerns to the Thai FDA or local public health authorities.

Making Your Decision

Choosing a cannabis clinic ultimately comes down to a combination of practical factors and personal comfort. Here is a framework to help you decide.

Start with the basics. Is the clinic licensed? Does it have a qualified practitioner? Does it issue proper PT 33 prescriptions? If the answer to any of these is “no” or “unclear,” move on.

Consider your specific needs. What condition or symptom are you addressing? Some practitioners have more experience with certain conditions. If you have a complex medical history or are taking multiple medications, a physician or pharmacist may be a better fit than other practitioner types.

Factor in practicality. Location, operating hours, language availability, and cost all matter. The “best” clinic is one you will actually visit regularly, not one that requires an inconvenient journey.

Trust your instincts. If something feels off — the consultation is too rushed, the staff seems more interested in selling than helping, or the environment does not feel professional — trust that feeling and try a different clinic.

Be willing to try more than one. Your first clinic visit may not be your last. Many patients visit two or three clinics before finding the right fit. There is nothing wrong with shopping around until you find a practitioner and clinic that meet your needs.

Thailand’s cannabis clinic landscape continues to mature and professionalize. The regulatory framework, while still evolving, has raised the baseline quality of care significantly compared to the unregulated period. By doing your research and asking the right questions, you can find a clinic that provides genuine medical cannabis care tailored to your needs.

Key Takeaways

• All cannabis flower purchases require a PT 33 prescription from a licensed practitioner. Any shop selling without one is operating illegally.
• Seven types of practitioners can prescribe cannabis in Thailand: physicians, TTM practitioners, Chinese medicine doctors, pharmacists, dentists, approved nurses, and veterinarians.
• Government hospital clinics offer the lowest prices but may have longer waits and limited English. Private clinics cost more but offer convenience and language support.
• A genuine consultation involves a medical history review, assessment, education, specific dosage guidance, and proper PT 33 documentation. Anything less is a red flag.
• Avoid clinics that sell without consultation, skip the PT 33, make cure claims, or pressure you into purchases.
• Follow-up care is essential. Choose a clinic that schedules follow-ups and adjusts your treatment over time.
• Verify legitimacy by checking for displayed licenses, proper PT 33 forms, and labeled products with FDA registration.
• Keep all your PT 33 forms — they are your legal authorization to possess cannabis products in Thailand.
