How to get a cannabis prescription in Thailand (PT33, 2026)

To get a cannabis prescription in Thailand, complete a medical assessment with an authorized Thai practitioner. Prepare your passport or Thai ID details, symptoms, medical history, current medicines and allergies. If cannabis is medically appropriate, the practitioner may issue Form PT33 for up to 30 days of treatment. Approval is not automatic.

The controlled-herb notification, effective from 26 June 2025, sets stricter conditions for cannabis flower and its medical use. In 2026, additional requirements are changing which types of service locations may receive new licences to dispense cannabis flower.

Cannabox's online application accepts adults aged 20 or older who can provide Thai ID or passport details and a genuine medical reason. This is the service's intake policy, not a statement of every patient's legal eligibility. Confirm where and how the assessment will take place before booking, especially if you have not yet arrived in Thailand. Cannabox medical consultations start at ฿500. Paying for a consultation does not guarantee approval or a prescription.

PT33 vs a medical cannabis card

If you are searching for how to get a medical cannabis card in Thailand, start with a medical assessment. The relevant document for prescribed cannabis flower is PT33, not a private membership card.

Document	Who provides it	Role in Thailand	What to check
PT33 (Form ภ.ท.33)	An authorized Thai practitioner after a medical assessment	The prescription record for medically appropriate cannabis flower; treatment period is no more than 30 days per issuance	Your identity, prescriber credentials, issue date, clinical assessment and treatment instructions; confirm dispensing arrangements
Private cannabis card or QR pass	A private service or membership provider	May help a service retrieve records; the card itself does not replace PT33 or authorize dispensing	Ask whether an actual Thai-issued PT33 exists, who assessed you and how the dispensing location receives it
Foreign prescription or medical card	An overseas practitioner or service	Supporting medical history for a Thai assessment; it does not replace Thai-issued documentation	Bring relevant records and medicine details; arrange a Thai assessment before seeking cannabis flower

Our guide to cannabis cards and PT33 explains how to check the document behind a private card or QR pass.

Choose the right medical route

Choose how you meet the practitioner, then confirm availability before booking.

Book before visiting a dispensary, or ask the shop to arrange telemedicine during your visit.

The practitioner assesses you by call or video. Shop staff cannot make the prescribing decision.

What happens at the dispensary?

1. Check in with the shop. If it arranges telemedicine, staff may help you register with its clinic provider and complete a patient form. Have your ID and health details ready, and ask where you can speak privately.
2. Speak with the practitioner. For a live consultation, you speak by phone or video with a practitioner who may be at another location. Explain your symptoms, medical history and medicines. They may request records or refer you for an in-person assessment; shop staff cannot approve treatment.
3. Allow time for document checks. If treatment is prescribed, ask how the shop will receive your PT33 and when it will be ready to check it. Staff must check your ID and prescription before dispensing. A consultation receipt or completed intake form is not a prescription.

Ask about fees and practitioner availability before visiting. Check-in and document arrangements vary by provider; one published telemedicine workflow illustrates the process. Medical clinics, including dispensaries operating as licensed clinics, must meet the applicable DTAM facility requirements.

Avoid pre-signed prescriptions

Do not accept a pre-signed blank PT33 that shop staff fill in without an individual medical assessment. In June 2026, Khaosod English reported DTAM's crackdown on forged and pre-signed prescriptions, including action against involved medical professionals. An official government warning on 17 August 2026 specifically warned dentists against signing PT33 in advance without examining or diagnosing the patient.

The three-step PT33 route

1. Prepare your details

Under DTAM’s patient-record requirements, PT33 records the patient's name, age, nationality and Thai ID or passport number. The practitioner completes the clinical assessment and treatment instructions.

For Cannabox's application, prepare:

PT33 explained

Tick each group when prepared. This is a preparation list, not an eligibility check.

0 of 3 groups prepared

Identification

• Thai ID or passport
• A clear document copy
• Photo holding the same ID

Health information

• Symptoms and past treatment
• Medicines and supplements
• Allergies and previous reactions

Follow-up contact

• LINE, WhatsApp or phone
• Relevant records if requested
• Share risks and your questions

For the ID upload, show the whole document clearly. Use your passport's photo page with all corners, name, photo and number visible; in the photo holding it, show your face and the same document together.

Use the consultation form or a clinic's verified patient system. Read its privacy notice before uploading and keep identity and medical records out of public chats. An uploaded ID or completed blank form is not a prescription.

2. Complete the medical review

Attend the online consultation or your clinic appointment. The authorized practitioner reviews your symptoms, history, medicines and risks, and decides whether to prescribe, request records or recommend other care. If treatment is appropriate, they set the dose, quantity and duration. Cannabox and dispensary staff cannot make that decision.

3. Use approved documentation correctly

If the practitioner approves treatment, follow the dosage, quantity, duration and other instructions recorded on the PT33 prescription.

Use the prescription only through a licensed service location permitted to dispense cannabis flower and retain the required patient and dispensing records.

Use our dispensary checklist before visiting a location found in the dispensary directory. A listing does not certify the establishment or its licence.

What does a cannabis prescription assessment cost?

Cannabox medical reviews start at ฿500 for an assessment by call and PT33 documentation if prescribed. This is the service's price, not a government fee or national clinic tariff. Check the final price and these separate costs before paying:

• Follow-up appointments: not included in the initial assessment.
• Original PT33 delivery: not included; confirm the fee, recipient and dispatch estimate if prescribed.
• Cannabis flower: purchased separately through licensed dispensing after the required checks.

See consultation details and fees and the refund policy. Other providers set their own fees.

How do I arrange a PT33 consultation?

Online before your visit: use the Cannabox application to provide patient details, medical information, documents, payment and consent. The team coordinates a practitioner assessment by call. Confirm where you must be for the assessment, especially if you have not arrived in Thailand.

Telemedicine during a dispensary visit: contact the shop first to ask whether it can arrange a remote practitioner, when the practitioner is available, which documents are needed and what the consultation costs. Allow time for the consultation and document checks before dispensing.

In-person clinic: book directly with a licensed clinic that offers cannabis consultations. Confirm the practitioner will be there, the appointment fee and whether a physical examination is needed. The same checks apply to a dispensary that has converted to a medical clinic.

Plan document delivery before travelling

If treatment is prescribed through Cannabox, confirm where the original PT33 will be sent. We can share Bangkok dispensary options, or coordinate dispatch to a licensed dispensary you choose. A directory listing does not verify its current licence.

Clinical review, document delivery and the dispensary's ID and prescription checks take place separately. Ask for each estimate and confirm that the shop has received the document before you visit. This guide promises no fixed turnaround.

What changed in 2026?

Thailand’s 2025 controlled-herb rules established the medical-use requirement for cannabis flower. Online cannabis-flower sales, vending-machine sales and cannabis advertising remain prohibited. Tourists must not buy, use, carry or transport cannabis flower without a valid prescription issued in Thailand. Tourism Authority of Thailand: notice for tourists

DTAM’s 2026 establishment guidance introduces a tighter medical-service model for new licences and renewals. The main public-facing categories are:

• Licensed clinics and healthcare facilities
• Licensed modern-drug pharmacies
• Licensed herbal-product shops
• Legally recognized folk-healer practice locations

Each category must meet its own professional-supervision, staffing, premises and recordkeeping requirements. DTAM medical cannabis establishment guidance

Existing cannabis businesses licensed under the earlier rules may continue operating under their existing permission until that licence expires. New applications and future renewals must meet the applicable 2026 requirements. DTAM 2026 medical cannabis FAQ

This transition means a location that previously operated as a conventional dispensary should not automatically be assumed eligible for future licensing. Patients should confirm that the selected location currently holds permission to dispense cannabis flower and can retain the required PT33 record.

Can tourists and expats apply?

Tourists and foreign residents with a legitimate medical reason may be assessed through a Thai medical pathway. Nationality alone does not determine approval.

A foreign prescription, medical cannabis card or doctor’s letter does not replace the Thai-issued documentation required for cannabis flower in Thailand.

Thailand’s official tourist notice states that visitors must not buy, use, carry or transport cannabis flower without a valid prescription issued in Thailand. If treatment is approved:

• Keep your Thai-issued documentation available.
• Follow the prescribed quantity and treatment duration.
• Use a licensed dispensing location.
• Do not take cannabis across an international border.
• Do not assume that a foreign cannabis card gives legal protection in Thailand.

Read the official tourist notice

Who can issue PT33?

PT33 must be issued by an authorized Thai practitioner acting within the treatment guidelines and professional scope applicable to their licence.

The official PT33 form identifies the following categories:

• Medical doctors
• Dentists
• Pharmacists
• Thai traditional medicine practitioners
• Applied Thai traditional medicine practitioners
• Traditional Chinese medicine practitioners
• Authorized folk healers

The diagnosis and prescription must comply with the medical-cannabis indications and treatment guidance applicable to that profession. See the official form and field guide below.

A dispensary cannot issue PT33 independently or promise that an application will be approved. The clinical decision belongs to the authorized practitioner.

How to check a provider before sharing records

Look for a service that:

• Conducts a real medical intake before any decision
• Identifies the authorized practitioner and professional category involved
• Asks about symptoms, history, medicines, allergies and relevant risks
• Makes clear that approval is not guaranteed
• Uses a verified patient system and provides a privacy notice
• Explains how approved documentation, dispensing and required records are handled

Avoid any service that promises instant approval, sells cannabis flower online or asks you to send passport and medical records through an unknown social-media account.

How to read the official PT33 form

The PorThor 33 prescription form, officially Form ภ.ท.33 or PT33, is shown below. This is a blank official form, not a completed prescription or instructions for choosing a dose.

PT33 explained

Choose a field group to locate it on the blank form.

Blank form - not an issued prescription

1. 01Prescriber and issue date

   Check the name, professional category, licence or certificate number and date.

2. 02Identity and assessment

   Patient details must refer to you. The practitioner records the clinical assessment.

3. 03Instructions and quantity

   Read the daily amount, treatment days and total together. Ask about unclear entries.

30 days maximum per issuance

A treatment-period limit, not a quantity in grams or an unlimited allowance. The practitioner may prescribe a shorter period.

Do not alter an issued prescription. Verify the issuer through a trusted contact. Source: Official DTAM PT33 form.

A form that looks complete is not proof of authenticity. Confirm the issuer and both patient and prescriber names with the issuing provider. Follow your own recorded dose; do not copy another person's dose or alter the document.

PT33 records and limits

The dispensing business must retain the prescription for at least one year from the date of issuance. Official DTAM PT33 form

PT33 is not:

• A recreational cannabis card
• An unlimited purchase pass
• A guarantee of approval
• Permission to buy cannabis flower online
• Permission to advertise or resell cannabis
• Permission to carry cannabis across an international border
• A guarantee that every location can dispense against the same record

Confirm the dispensing and recordkeeping arrangements before purchasing cannabis flower.

Safety before you apply

Tell the practitioner about:

• Prescription and non-prescription medicines
• Supplements and herbal products
• Sedatives or sleeping medicines
• Alcohol or other substance use
• Allergies or previous adverse reactions
• Pregnancy or breastfeeding
• Heart or cardiovascular conditions
• Any history of anxiety, panic, psychosis, bipolar disorder or depression

Do not drive, operate machinery or perform safety-sensitive work after using cannabis.

Cannabis may cause impairment, anxiety, dizziness, changes in perception or other adverse effects. A medical review does not make cannabis risk-free. See the NCCIH evidence and safety overview.

Seek urgent medical assistance if you experience severe confusion, chest pain, loss of consciousness, difficulty breathing, extreme agitation or thoughts of harming yourself or someone else.

This guide is educational and does not replace individual medical or legal advice. Regulations and clinical standards may change. Check DTAM’s current public guidance or speak with an appropriately licensed Thai practitioner before acting.
