Under Thailand's current controlled-herb framework, cannabis flower may be dispensed only against a PT33 issued by an authorised practitioner after assessment and diagnosis. Telemedicine can make access convenient, but the consultation is clinical and issuance is never automatic.
Here's what the PT33 actually is, why it exists, and how the process really works in 2026 — because a lot of the confusion online is people guessing.
What Is a PT33 Prescription?
The PT33 is the medical prescription that brings a cannabis flower purchase inside Thailand's current legal framework. When the country moved cannabis back toward a medical-only model in 2025, the prescription requirement was the mechanism. It's the document that makes your purchase legal rather than a grey-area transaction.
Practically, it means a licensed practitioner has assessed you and signed off on the purchase. That's the gate every legal flower sale now passes through. No PT33, no legal flower — which is exactly why buying from an unlicensed source, who can't issue one, carries the risk it does.
Do Tourists Qualify?
Foreign visitors are not automatically excluded, but eligibility is not just an age-and-ID formality. You must be 20 or older with valid ID or a passport, and an authorised practitioner must conduct a genuine assessment and decide that cannabis is medically appropriate. The practitioner may request relevant medical information or decline to prescribe.
A visitor may be assessed without an existing Thai medical record, but age and a passport alone do not guarantee eligibility. The practitioner must determine that the use fits applicable professional indications.
The Old Way vs. How It Actually Works Now
The version of this that scares people is the multi-step one: find a clinic, book a consultation, get a certificate, then take that certificate to a separate dispensary to actually buy. That sequence does exist at some places, and it's a genuine hassle — two locations, two queues, possibly two days.
It's also avoidable. The cleaner model is to handle the prescription where you buy, in one visit.
Stash can facilitate an on-site telemedicine consultation with an authorised practitioner. The current service is usually around 10–15 minutes and costs 100 THB. The practitioner—not the shop—assesses eligibility and decides whether to issue a PT33.
Step by Step, Start to Finish
What an actual visit looks like:
- Walk in. No appointment needed. Bring your passport or ID — you'll need to be 20 or older.
- Complete the consultation. Give accurate information about symptoms, history, medicines, and intended use. The practitioner assesses and records a diagnosis.
- Pay the consultation fee. 100 THB, separate from whatever product you buy.
- If prescribed, follow the PT33. It states the product directions, daily amount, number of days, and total quantity. One issuance may cover no more than 30 days.
- Keep your documentation. Carry the PT33 or a copy with the dispensed product.
The service is designed to be accessible, but it remains a medical decision. No shop should promise approval before the practitioner assesses you.
Where to Do It
At Stash BKK, every branch can facilitate the PT33 telemedicine assessment during operating hours, subject to practitioner availability. On Nut, Ari, and Ekkamai run 24/7; Chinatown runs 2PM to 2AM.

FAQ
What is a PT33 prescription in Thailand?
It's the medical prescription required to legally buy cannabis flower in Thailand since June 2025, issued by a licensed practitioner. It's what makes a flower purchase legal under the current framework — without it, a sale sits outside the law.
Can tourists get a PT33 prescription?
Tourists may be assessed. You must be 20 or older with valid ID, and an authorised practitioner must diagnose and decide that cannabis is medically appropriate. Eligibility is not automatic.
How long does the cannabis prescription take?
At Stash BKK, the on-site telemedicine consultation typically takes around 10–15 minutes and normally does not require an appointment, subject to practitioner availability. Timing and issuance are not guaranteed.
How much does a cannabis prescription cost in Thailand?
The current Stash-facilitated consultation fee is 100 THB, separate from any dispensed product. A legitimate separate clinic is not a compliance warning; what matters is that an authorised practitioner performs a real assessment.
Do I need a prescription every time I buy?
A PT33 may cover no more than 30 days and specifies the daily amount, number of days, and total quantity. Repeat dispensing cannot exceed those terms; a later purchase may require a new assessment and prescription.
Can I just buy without a prescription somewhere?
Only outside the legal framework, from an unlicensed seller — which carries real legal risk and gives you no documentation, no quality information, and no recourse. The prescription exists for a reason; the licensed route is the clean one.
