If you want to use cannabis prescription in Bangkok, you need more than a dispensary displaying cannabis flower. The store must be able to check your valid Thai PT33, confirm that the prescription remains active, verify the amount you are authorised to purchase and record the transaction correctly.
Thailand’s official guidance for residents and tourists states that cannabis flower is controlled and may only be purchased with a valid prescription issued in Thailand by an authorised medical professional. The amount supplied must be medically necessary and limited to a treatment period of no more than 30 days.
The ThaiCannaMed Green Network helps patients find participating Bangkok dispensaries familiar with the ThaiCannaMed consultation, prescription-verification and reporting process. It is usually the simplest starting point when you want to use cannabis prescription in Bangkok, but a Green Network listing is not a government licence, legal guarantee or blanket approval of every product sold by the store.
What Is a PT33 Cannabis Prescription?
PT33, officially Form ภ.ท.33, is the prescription issued by an authorised practitioner following an individual medical assessment. It records the patient’s information, treatment directions, authorised quantity and treatment period. A genuine PT33 must follow a real consultation. You cannot lawfully buy an approval from a dispensary employee, complete a blank prescription yourself or obtain a guaranteed PT33 as part of a retail purchase. ThaiCannaMed works with licensed Thai Traditional Medicine practitioners operating through Wonderland Clinic. During the consultation, the practitioner reviews the patient’s symptoms, relevant medical history and current medication before deciding whether cannabis is appropriate. Approval is never guaranteed. ThaiCannaMed gives approved patients digital access to their prescription information. When you use cannabis prescription in Bangkok, keep that digital access available together with your identification, purchase receipt and original product packaging.

Bangkok Dispensaries in the Green Network
Current ThaiCannaMed information identifies the following established Green Network locations in Bangkok:Cloud Nine Asoke
Cloud Nine Asoke is a central Bangkok option for patients staying around Asoke, Nana and the wider Sukhumvit area. Its Green Network connection allows customers to access the ThaiCannaMed consultation pathway and use approved prescription information through the participating workflow.Wonderland Bangkok
Wonderland is located on Sukhumvit Soi 5 and is connected with Wonderland Clinic, which operates the licensed clinical side of ThaiCannaMed. Patients who prefer direct assistance can ask the team about the consultation and purchasing process.Kush House
Kush House is located on Sukhumvit Soi 22 near EmSphere. It is listed as a verified Green Network dispensary with medical-consultation support available through the network.Mary Jane Nana
Mary Jane Nana provides another Green Network option in the lower Sukhumvit area. Patients should check the live directory for current hours, contact information and consultation availability before visiting.Mary Jane Patpong
Mary Jane Patpong serves patients around Silom and Patpong. As with every location, customers should confirm the current store information and ensure that the product and requested quantity are covered by their active prescription. Green Network locations can change, and new stores may join while others may leave or update their details. Always use the live Green Network directory instead of an old lnk.bio list or copied collection of shop names. This is especially important when deciding where to use cannabis prescription in Bangkok. Old articles may include businesses outside Bangkok, locations that are no longer participating or stores whose prescription procedures have changed.What Happens at a Green Network Dispensary?
The exact experience may vary slightly by location, but an authorised purchase generally follows these stages.1. Present Your Identification
Thai nationals should have a valid Thai identification card. Tourists and expats should have a valid passport. ThaiCannaMed currently accepts consultation requests from adults aged 20 or over. Patients who are pregnant or breastfeeding should not assume cannabis is appropriate and must disclose this information during the assessment.2. Provide Access to Your Active PT33
The dispensary checks the prescription details and confirms that they match the customer. A screenshot alone should not be treated as automatic proof if the store cannot verify its status or remaining quantity.3. Confirm What You Are Authorised to Purchase
The PT33 records the quantity authorised by the practitioner. The dispensary can supply only an amount covered by the active prescription and must account for previous purchases. A 30-day treatment period is not an automatic right to buy 30 grams or make unlimited purchases. The practitioner may authorise less, and every purchase reduces the remaining allowance.4. Complete the Authorised Transaction
Once the prescription has been verified, the dispensary supplies the permitted amount and records the transaction. The patient should keep the receipt and original packaging.5. Check the Remaining Quantity and Expiry Information
Patients should know how much remains available and when the PT33 expires. Unused quantity should not be treated as automatically transferring to a new treatment period. This process makes it easier to use cannabis prescription in Bangkok without relying on vague assurances from counter staff.Can You Complete the Consultation Inside the Dispensary?
Participating Green Network locations can provide access to the ThaiCannaMed consultation pathway. The medical assessment is conducted privately by a licensed Thai Traditional Medicine practitioner operating through Wonderland Clinic—not by the budtender or dispensary manager. The usual in-store process is:- Scan the ThaiCannaMed QR code.
- Complete the patient intake on your phone.
- Join a private consultation.
- Wait for the practitioner’s decision.
- Receive digital PT33 information if approved.
- Allow the dispensary to verify it.
- Complete only the authorised purchase.
Arrange Your PT33 Before Visiting a Shop
You do not have to begin inside a dispensary. Patients can start through the ThaiCannaMed Patients Hub before choosing where to use cannabis prescription in Bangkok. The complete journey — from intake form to prescription — takes approximately 5–15 minutes. The doctor consultation itself usually takes approximately 1–5 minutes after advance intake is completed. Our doctors are available daily from 10 AM to 2 AM Thailand time (GMT+7). Current online consultation prices are:- First consultation: THB 600
- Renewal consultation: THB 400
Can Tourists Use a Foreign Medical Cannabis Card?
No. A foreign cannabis prescription, medical card or doctor’s letter does not replace the Thai PT33 needed within Thailand’s controlled-cannabis system. Tourists can request an assessment using a valid passport. If an authorised practitioner in Thailand approves treatment, the tourist can receive a PT33 and then use cannabis prescription in Bangkok at a compatible registered dispensary. Visitors should also remember:- Cannabis flower must not be carried across an international border.
- A Thai prescription does not permit cannabis on an international flight.
- Cannabis should not be smoked in public.
- Products should remain in their original packaging.
- The patient should retain the prescription and receipt.
- Cannabis must not be shared, resold or purchased for another person.
Can You Use the Same PT33 More Than Once?
A PT33 may cover a treatment period of no more than 30 days. It may support more than one purchase during that period if:- The prescription remains active
- The authorised quantity has not already been exhausted
- The dispensary can verify the remaining amount
- Every transaction is properly recorded
- The requested purchase remains within the treatment directions
What Can You Buy with a PT33?
A PT33 is principally associated with controlled cannabis flower prescribed for the patient’s personal medical treatment. It should not be treated as blanket permission to purchase every cannabis-related product displayed in a dispensary. Oils, extracts, foods, gummies, cosmetics and herbal products may fall under different Thai FDA or regulatory categories. Their legality depends on factors including formulation, THC concentration, registration, manufacturing permission and labelling. Patients should ask:- Is this product covered by my prescription?
- Is it registered or otherwise authorised?
- Who manufactured it?
- What are its THC and CBD levels?
- Is there Thai-language product information?
- Can the dispensary show its source and supporting documentation?
Why Use the Green Network?
The Green Network is valuable because participating dispensaries already understand the ThaiCannaMed patient pathway. That can reduce confusion when you want to use cannabis prescription in Bangkok, particularly if you are a tourist or first-time patient. The network provides:- A live directory of participating dispensaries
- Access to the ThaiCannaMed consultation pathway
- A familiar prescription-verification process
- Staff accustomed to prescription-holding patients
- Connections between PT33 prescriptions and transaction records
- Every patient will be approved
- Every listed shop will accept every outside prescription
- Every product is covered by PT33
- Every location has identical prices or opening hours
- Every transaction will be completed instantly
- Membership provides the patient with legal immunity
Should You Avoid Every Non-Network Dispensary?
Not necessarily. Other registered dispensaries may be able to verify and accept a valid PT33. The difference is that Green Network locations are already connected to the ThaiCannaMed pathway. If you visit another dispensary, confirm in advance that it can verify your prescription, remaining allowance and expiry information. Walk away if a shop:- Offers flower without checking PT33
- Promises a guaranteed prescription
- Uses a blank or pre-signed form
- Tells you to invent symptoms
- Cannot identify the product’s source
- Encourages public smoking
- Suggests taking cannabis out of Thailand
- Refuses to provide a receipt
Staying Within the Rules After Your Purchase
After purchasing cannabis flower:- Keep your PT33 digitally accessible.
- Retain the purchase receipt.
- Keep the product in its original packaging.
- Carry only the amount supplied under the active prescription.
- Use cannabis privately without disturbing other people.
- Do not drive or ride a motorbike while impaired.
- Do not give or sell cannabis to anyone else.
- Do not take cannabis across an international border.
