Do you need a prescription to buy cannabis in Pattaya?

The short version

• Adults 20 and over only; identification is checked every visit, including for returning customers.
• The notifications published in June 2025 tie the retail sale of cannabis flower to a prescription.
• The prescription has to be issued by a practitioner licensed in Thailand — not by your doctor at home.
• Bring the original document, not a photograph of it on your phone.
• The notifications describe supply measured in days rather than in weight; thirty days is the figure quoted throughout.
• Nothing about this can be arranged online: sale through electronic channels is prohibited.
• The controlled-herb notice does not permit sale to anyone under 20, to a pregnant woman, or to a woman who is breastfeeding — the rule as written, not a shop policy.

What changed, in one paragraph

Official source

Until the middle of 2025 a visitor could walk into a shop in Pattaya, show a passport, and buy flower with no further paperwork. The notifications published at the end of June 2025 closed that route: retail sale of cannabis flower is now tied to a prescription, shops keep records of what they sell and to whom, and the herb is handled as a controlled substance rather than as an ordinary retail good.

Everything else on this page follows from that one change. If a page you are reading does not mention it, the page is describing 2023 — and there is a great deal of 2023 still sitting in search results, on forum threads and in the cached descriptions of shops that have since changed how they operate.

Which document, and who writes it

Practical caution — not a legal conclusion

The requirement points at a practitioner licensed under Thai law. In practice that means a document issued inside Thailand, on the practitioner's own paperwork, naming you. A licensed shop is not the issuer — it is the party that has to see the document and keep a record of the sale, which is why nobody at a counter can write one for you no matter how the question is phrased.

The form has a name worth knowing: ภ.ท.33, transliterated PT 33 — the controlled-herb prescription form that cannabis flower is dispensed against. Asking a clinic for the controlled-herb prescription rather than for "a cannabis prescription" is the phrasing that gets you the right piece of paper. Form numbers are administrative and can be renumbered, so confirm on the day rather than arguing from a forum thread; what you leave with is the document itself, in your hand, in its original form.

Photographs, screenshots and photocopies are not the document. This is the single most common reason a visit ends at the counter rather than at the till: the paper is real, it exists, and it is in a hotel safe on the other side of town.

Where the document is actually obtained

Practical caution — not a legal conclusion

The notices say who may write the document, not where to go, so this block is practical caution rather than a restatement of the rule. In practice a visitor gets it the same way a resident does: from a practitioner registered in Thailand, at a licensed clinic or through a consultation with a registered practitioner, and the ministerial regulation of April 2026 requires that person to be present at the premises during opening hours.

A passport is the identification a visitor is asked for. Thai residency, a work permit and a long-stay visa are not part of the requirement described in the notices, and nothing in them creates a separate route or a separate document for foreigners. The prescription is issued in your name, and the original stays with you — it is your document, not the shop's.

This shop is not a clinic and has no arrangement with one. We do not issue the document, we do not book the consultation, and we cannot say in advance what any practitioner will or will not write. What a counter can do is look at what you already hold and tell you whether it is the right kind of paper — which is worth asking by message before you cross the city.

A prescription from home does not transfer

Practical caution — not a legal conclusion

A prescription written by a doctor in your own country is a document about you, but it is not the document Thai retail rules ask for, and no counter can convert one into the other. The same is true of a medical cannabis card from another jurisdiction, of a letter from a clinic, and of an app that displays a card on a screen.

This catches out visitors from countries where cannabis is legal at home more than anyone else, because they arrive with paperwork they are used to having accepted. It is worth planning around before the flight rather than in a doorway on a hot afternoon.

The thirty-day figure and what it is not

Official source

The notifications describe supply in terms of days rather than weight, and thirty days is the number quoted throughout the official texts. That is a ceiling on what a prescription covers, not an allowance you are entitled to, and it is not a promise about what any particular shop has on the shelf on any particular day.

It is also not a customs allowance. Nothing about a prescription creates a right to take cannabis out of Thailand, and a document that is valid at a counter in Pattaya has no effect at an airport. That subject is covered in the legal guide on this site, with the government sources attached.

What the check looks like at our counter

Practical caution — not a legal conclusion

Three things happen and they happen in the same order every time. Age first: twenty or over, no discretion, no exceptions for people who look older. Identity next: a passport for visitors, a Thai identity card for residents. Paperwork last: the prescription, in its original form, read rather than glanced at.

Then the conversation starts — what you are looking for, what is on the shelf today, what is worth comparing against what. That order is deliberate. A shop that discusses the shelf first and the documents afterwards has told you which set of rules it lives under, and it is not the set that keeps a licence on the wall.

If any part of this goes wrong, it is better to find out by message before crossing the city than at the door. Write and describe what you are holding; you will get a straight answer about whether it is the right kind of document.

How to tell a licensed counter from a seller

Practical caution — not a legal conclusion

A licensed shop has a licence displayed where customers can read it, asks for identification without being prompted, and asks about paperwork before it asks what you want. It sells in a fixed premises with a sign and an address that matches what its listing says. It does not sell through a messaging app, does not meet people outside, and does not deliver.

A seller who offers to bring something to your hotel, who takes an order in chat, or who waves the document question away is not offering you convenience. They are telling you that their operation sits outside the licensing regime — and everything that follows from that, including what happens if the transaction goes wrong, sits outside it too.

The check costs nothing. Ask to see the licence before you buy anything. In a shop that has one, this is an unremarkable request and takes ten seconds.

Why this website has no menu, no prices and no ordering

Official source

The same body of rules that introduced the prescription requirement also restricts advertising a controlled herb through public channels and prohibits sale through electronic ones. A website with a price list, a stock page or a payment button is not being helpful; it is publishing exactly what the notifications restrict.

So this domain carries none of it, in any of its seven languages. What is on the shelf changes daily and is answered in a message or at the counter, which is both the lawful channel and, as it happens, the one where you get a useful answer rather than a stale page.
