Thailand’s cannabis market has thinned dramatically, and in 2026 the fastest way to know whether the shop in front of you is legal is no longer a guess. The Department of Thai Traditional and Alternative Medicine (DTAM) has published every properly registered cannabis outlet on its official website and pinned each one’s GPS coordinates, with the licence’s expiry date shown alongside. If a shop is not on that list, it is considered not properly registered — and its operators can be arrested.
That single fact makes verification simple. Below is how to run the check yourself, what a compliant outlet should look like once you walk in, and why authorities are moving quickly against an estimated 6,000-plus illicit and expired-licence shops nationwide.
Why the registry is the test
Authorities, working with police and local officials, are using a GPS-based system to map licensed outlets and accelerate a crackdown on shops that are unlicensed or trading on expired paperwork. The registry is the public face of that system: every legitimate outlet appears on it, at a fixed location, with a licence expiry date. A shop’s presence — or absence — is the quick public test of legality.
The old assumption that a green-leaf sign and an open door meant a shop was legal no longer holds. Many outlets kept operating after their licences lapsed. The registry cuts through that: if the shop is not listed at its actual location, treat it as unregistered.
How to verify a shop in under 2 minutes
- Open DTAM’s official website and find the public registry of licensed cannabis outlets.
- Search by the shop’s location or name, and match the pinned GPS coordinates to where you are actually standing. A listing at a different address does not cover this storefront.
- Check the licence expiry date shown against today’s date. An expired date means the outlet is no longer authorised, even if the door is open.
- Look for the official identification sticker on the premises — regulators are issuing stickers that display each outlet’s licence status and expiry date.
- If the shop is not listed, is listed at a different address, or shows an expired licence, do not buy — and consider reporting it (see below).
If all four checks pass — listed, correct location, current date, matching sticker — the outlet has cleared the basic legality test.
What a compliant outlet looks like inside
Registry status is the first filter. A fully compliant 2026 outlet also meets the operating rules that define the medical model, so use these as a second check once inside:
| Check | What a compliant shop shows |
|---|---|
| Licensed practitioner | A licensed practitioner is on-site during operating hours |
| Prescription only | Cannabis is sold against a PT 33 prescription only, capped at a 30-day supply |
| Sourcing | Flower is sourced from GACP-certified farms |
| No advertising | No advertising or promotion of cannabis |
| No recreational sales | No sales for recreational use |
A storefront selling to walk-in tourists with no prescription, no practitioner, and open advertising is displaying the exact signals the crackdown targets — whatever any wall certificate claims.

What happens to shops that aren’t listed
If an outlet is not on the DTAM registry, it is considered not properly registered, and its operators can be arrested. Enforcement is not theoretical: authorities are actively accelerating action against the estimated 6,000-plus illicit and expired-licence shops, using the GPS registry to find them. A shop’s absence from the list is exactly what inspectors act on.
This is also why the identification stickers matter. They let an inspector — or a customer — confirm status at the door without opening a laptop, and they make an unstickered, unlisted shop conspicuous.
The market context: why so many shops are exposed
The registry crackdown lands on a market already in steep decline. Thailand peaked near 18,000 shops. The renewal collapse that followed is the reason so many outlets are now trading on expired or missing licences.
| Metric | Figure |
|---|---|
| Shops at peak | ~18,000 (18,433 recorded) |
| Licences expired in 2025 | 8,636 |
| Renewed in 2025 | 1,339 (~15.5%) |
| Shops closed by Feb 2026 | 7,297 |
| Shops still operating (Feb 2026) | ~11,136 |
A second wave is coming. About 12,000 distribution licences are valid for 2026–2028, but roughly half are set to expire during 2026 — a second round of attrition that will push more shops off the registry unless they renew and stay compliant. Owners weighing that decision should start with our business compliance hub.
If you spot a shop that fails the check
You can report a suspected illegal outlet to the ONCB hotline on 1386, which operates 24/7. It also helps to note the shop’s exact location, since the enforcement system is built around GPS coordinates.
Two related enforcement stories are worth reading alongside this: the crackdown on fake PT 33 prescriptions, and the revived Cannabis and Hemp Act that would put the whole regime on a statutory footing. Patients checking their own access can start with our medical cannabis overview.
The bottom line: in 2026, a legal cannabis shop is one you can find on DTAM’s registry, at its pinned location, with a licence that has not expired. Everything else is a risk — to the operator, and to you.
This article is general information, not legal advice. Cannabis rules in Thailand are changing quickly. Verify a shop’s current status on DTAM’s official registry, and confirm requirements with DTAM or a qualified professional before making business or medical decisions.
