If you are looking for a cannabis prescription in Thailand, you need a genuine medical assessment by an authorised healthcare practitioner in Thailand. A foreign prescription, medical card or doctor’s letter does not replace the Thai documentation required for cannabis flower. If treatment is approved, the practitioner issues a PT33 stating what has been authorised and for how long.
ThaiCannaMed provides a private consultation pathway for Thai residents, expats and tourists. A first online consultation currently costs THB 600, normally lasts around 5–15 minutes and is generally available daily from 10:00 AM until 2:00 AM Thailand time. Approval is not guaranteed: the practitioner must decide independently whether cannabis treatment is appropriate.
How to Get a Cannabis Prescription in Thailand
There are two ThaiCannaMed routes for obtaining a cannabis prescription in Thailand: arrange the medical consultation online or access the consultation process while visiting a participating Green Network dispensary.
Both routes lead to an assessment with a licensed Thai Traditional Medicine (TTM) doctor working through Wonderland Clinic. The TTM doctor reviews the patient’s information and makes the clinical decision. Dispensary employees cannot diagnose the patient, decide whether they qualify or alter the prescription.
Route 1: Arrange the Consultation Online
The online route is useful when you want to complete the medical assessment before visiting a dispensary.
- Complete the ThaiCannaMed medical intake form.
- Provide the appropriate identification.
- Join a private video consultation with the TTM doctor.
- Answer questions about your symptoms, relevant medical history, current medication and previous cannabis use.
- If treatment is approved, receive the digital PT33.
- Present the prescription to a registered dispensary for verification and authorised supply.
The current online fee is THB 600 for a first consultation and THB 400 for a renewal assessment. The video consultation itself normally takes approximately 5–15 minutes once the required information is ready. Demand, incomplete documentation or the need for further clinical questions can make the overall process longer.
Route 2: Use the In-Store Consultation Pathway
Participating Green Network dispensaries provide access to the ThaiCannaMed consultation pathway in store. The patient scans the ThaiCannaMed QR code, completes the intake form and joins a private video consultation with the TTM doctor.
When the required information is ready, the complete process typically takes around 15–20 minutes, including intake, consultation and issue of the PT33 if approved. This is a typical service time, not a guaranteed waiting time or a promise that a prescription will be issued.
At some participating stores, the consultation may be included with a qualifying bundle. Terms vary by location. The Green Network is currently expanding, with participating locations available in Bangkok and Phuket. Patients can check the current Green Network directory before travelling to a store.
What You Need for the Consultation
For the ThaiCannaMed process:
- Thai nationals provide a Thai ID card.
- Tourists and expats provide a valid passport.
- Proof of Thai residency is not required.
- A foreign cannabis prescription or medical card cannot replace a Thai PT33.
- Patients should disclose relevant medication, diagnoses, medical history and previous adverse reactions honestly.
These identification and intake points describe ThaiCannaMed’s consultation process. They should not be presented as a complete statement of every legal or administrative requirement that may apply to every healthcare provider in Thailand.
What Happens During the Medical Assessment?
Anyone seeking a cannabis prescription in Thailand should expect a real clinical conversation rather than automatic approval. The TTM doctor may ask about:
- The symptoms for which treatment is being considered.
- How long those symptoms have been present.
- Previous treatment or existing diagnoses.
- Current prescription and non-prescription medication.
- Previous cannabis use and unwanted effects.
- Other information relevant to treatment safety.
Patients should describe their circumstances in their own words. ThaiCannaMed staff and dispensary employees must not coach people to report particular symptoms, tell them how to secure approval or advise them to stop existing medication.
The practitioner may approve treatment, request further information or decide that cannabis is not appropriate. Paying for a consultation does not buy a prescription; it pays for access to the medical assessment.
What Does a PT33 Authorise?
If the practitioner approves a cannabis prescription in Thailand, the PT33 records:
- The patient’s details.
- The condition being treated.
- The daily quantity.
- The total authorised quantity.
- The treatment period.
The prescription can cover no more than 30 days of treatment. The practitioner decides the actual period and quantity according to medical need. The 30-day limit is not an automatic allowance, and unused quantity does not give the patient permission to obtain more than the prescription authorises.
The PT33 allows a registered dispensary to verify what has been prescribed and supply within that allowance. It does not authorise buying for another person, reselling cannabis or taking it across an international border.

What Happens at the Dispensary?
The clinic and dispensary perform separate jobs. The practitioner completes the medical assessment and determines the prescription. The dispensary verifies the PT33, supplies no more than the authorised amount and records the transaction.
Joining the Green Network does not remove a retailer’s legal responsibilities. Each dispensary remains responsible for its own licence, verification procedures, reporting, supply records and document retention. The dispensing location must retain the PT33 documentation for at least one year.
ThaiCannaMed’s guide to PT28 and PT33 cannabis compliance explains the difference between the patient prescription and the business records associated with supply.
How Much Does a Cannabis Prescription in Thailand Cost?
The current ThaiCannaMed prices are:
- First online consultation: THB 600.
- Online renewal assessment: THB 400.
- In-store consultation: may be included with a qualifying bundle at some Green Network dispensaries.
The fee covers the consultation service. It does not guarantee approval and does not automatically include cannabis flower. Product prices and qualifying-bundle terms are set separately by the participating dispensary.
How Long Does the Process Take?
ThaiCannaMed’s usual service times are:
- Private video consultation: approximately 5–15 minutes.
- Complete in-store pathway: typically around 15–20 minutes when the required information is ready.
- Consultation availability: generally daily from 10:00 AM until 2:00 AM Thailand time.
These are typical times, not deadlines. Waiting can be longer when demand is high, information is missing or the practitioner needs to examine a clinical issue in greater detail.
How to Use the Prescription Responsibly
After receiving a cannabis prescription in Thailand, patients should keep the PT33 accessible together with proof of the authorised purchase. They should possess only the quantity supplied under the active prescription and follow the practitioner’s directions.
Official guidance from Thailand’s Division of Medical Cannabis advises patients to carry the prescription or a copy when possessing cannabis flower for treatment. It also states that private use must not create smoke, odour or disturbance for other people.
Do not take cannabis onto an international flight or across a national border. Thailand’s official guidance for tourists warns visitors not to assume that openly displayed cannabis is automatically lawful to purchase.
Frequently Asked Questions
Can Tourists Get a Cannabis Prescription in Thailand?
Tourists can use a valid passport to complete the ThaiCannaMed consultation. The TTM doctor must assess the individual case, and a PT33 is issued only if treatment is approved.
Can I Use a Prescription From Another Country?
A foreign prescription, cannabis card or doctor’s letter does not replace a PT33 issued through an authorised practitioner in Thailand.
Is Approval Guaranteed?
No. The practitioner can decline treatment or request additional information. Neither paying the consultation fee nor visiting a participating dispensary guarantees a prescription.
Can Dispensary Staff Approve My Application?
No. Dispensary staff can help patients access the process and can verify an issued PT33, but they cannot diagnose, prescribe, coach symptoms or influence the TTM doctor’s decision.
How Long Is a PT33 Valid?
It can cover no more than 30 days of treatment. The actual duration and authorised quantity are determined by the practitioner and recorded on the prescription.
Can I Obtain the Prescription Before Travelling to Thailand?
ThaiCannaMed can begin its online consultation process before a planned visit, subject to the service’s current requirements and practitioner availability. Receiving a digital PT33 does not permit cannabis to be carried across an international border. Cannabis flower must be obtained through an appropriately registered dispensary in Thailand.
Is My Medical Information Private?
The medical discussion should take place privately. ThaiCannaMed states that patient information is managed within Thailand’s PDPA framework. Patients should review the applicable privacy information and ask how their information will be used before submitting sensitive records.
Start Your ThaiCannaMed Consultation
To apply for a cannabis prescription in Thailand, start a private ThaiCannaMed consultation. Complete the intake information honestly, provide the appropriate identification and allow the licensed TTM doctor to determine whether treatment is suitable.
Getting a cannabis prescription in Thailand through a genuine medical pathway gives the patient clear documentation and separates the practitioner’s clinical decision from the dispensary’s retail role. ThaiCannaMed makes that pathway accessible online and through participating locations while preserving the essential safeguard: every prescription remains subject to an individual medical assessment.
