Since June 2025, buying cannabis flower in Thailand legally requires a prescription — specifically a PT33, issued by a licensed practitioner. If you've read that and pictured booking a clinic appointment, sitting in a waiting room, and coming back another day, relax. For most people it's nothing like that. Done properly, the whole thing takes about as long as ordering a coffee.
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?
Yes. This is the part people get wrong. The PT33 isn't a residents-only system or some bureaucratic membership you need to sign up for in advance. Visitors can get one. You need to be 20 or older and have a valid ID or passport, and you need a practitioner to issue the prescription. That's the whole eligibility bar for the vast majority of people who walk in.
You don't need a pre-existing Thai medical record, a local doctor, or paperwork from home. If you were worried this was a barrier built to keep tourists out of the legal market, it isn't.
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.
Cannabis flower requires a PT33 medical prescription under current Thai law. We handle this on-site via our DTAM-endorsed telemedicine platform — a quick consultation with a licensed practitioner over video, right there at the shop, the same hour you arrive. No separate clinic visit, no second trip. Around 10–15 minutes, 100 THB.
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.
- Do the consultation. A short telemedicine consult with a licensed practitioner over video, on-site. This is the PT33 step. It's brief and straightforward, around 10–15 minutes.
- Pay the consultation fee. 100 THB, separate from whatever product you buy.
- Choose your cannabis. Once the prescription's in place, you look at the menu, smell a few things, and the staff help match it to what you're after — sleep, daytime, something lighter.
- Leave. Done, legal, and you didn't have to cross town twice.
That's it. The thing people brace for as a medical ordeal is, in practice, a ten-minute step at the counter.

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?
Yes. You need to be 20 or older with a valid passport or ID, and a licensed practitioner has to issue it. No prior Thai medical record or local doctor is required. Stash BKK provides the consultation on-site via DTAM-endorsed telemedicine.
How long does the cannabis prescription take?
At Stash BKK, the on-site telemedicine consultation takes around 10–15 minutes, same hour you walk in. There's no separate clinic visit and no appointment needed.
How much does a cannabis prescription cost in Thailand?
At Stash BKK the on-site PT33 consultation is 100 THB, separate from the cost of any product you buy. Be cautious of any setup that sends you to a separate clinic first — that's extra friction you don't need.
Do I need a prescription every time I buy?
The PT33 framework governs legal flower purchases, so plan to handle the consultation as part of buying rather than assuming a one-time sign-up covers you forever. Ask the staff on your visit how it applies to repeat purchases — they'll walk you through it.
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.
