How to Check a Licensed Cannabis Shop in Thailand (2026): Licence Lookup, Red Flags and Reporting

Quick summary

• Cannabis flower is a controlled herb: only licensed outlets may sell it, and buyers need a practitioner's prescription.
• The main lookup tools are DTAM's MC-GIS map (cannabis-gis.dtam.moph.go.th) and the Mor Prom app.
• The Public Health Minister said on 22 Sep 2026 that shops not in the system should be presumed illegal.
• A compliant outlet is a clinic, pharmacy, herbal-product shop or certified folk healer, with trained staff and odour/smoke control.
• Online sales, delivery, vending machines and advertising are all illegal.
• Report suspected shops via LINE @traffyfondue or call 02 257 7042 (office hours).

Shops with cannabis-leaf signs are still easy to find in Bangkok and tourist areas. But since a new Ministerial Regulation took effect on 30 April 2026 and the Ministry of Public Health stepped up inspections, knowing whether a shop is legal matters more than ever. This guide explains how to check a licensed cannabis shop in Thailand, using what the authorities have told the press: the lookup system, signs of a compliant outlet, red flags and how to report. cannabis-official.com is an independent news site and does not endorse or recommend any shop.

Step 1: Look the shop up on MC-GIS and Mor Prom

The Department of Thai Traditional and Alternative Medicine (DTAM) runs a map called Medical Cannabis GIS (MC-GIS) at cannabis-gis.dtam.moph.go.th. According to Matichon (22 Apr 2026), it shows licensed shops and grow sites, and any shop on the map must hold a valid licence to sell and process cannabis and be operating normally.

On the system's page you can filter by:

• Data type: establishments or grow sites
• Status: operating, closed, licence suspended or licence revoked
• Health region and province

DTAM also says (Matichon, 19 Jun 2026) the Mor Prom app can be used to check shops, grow sites and licence expiry dates. The simplest habit: search for the shop name and province before you walk in, and make sure its status is "operating", not "suspended" or "revoked".

For scale: April 2026 figures put cumulative establishments at 18,517, of which 7,131 closed in 2025 for not renewing, leaving 11,386 operating legally. On 22 Sep 2026, Public Health Minister Pattana Promphat said more than 10,000 locations were recorded and that any shop not in the system should be presumed illegal.

Step 2: Check the type of premises and licence

The Ministerial Regulation on controlled-herb licences for commerce (No. 2) of 2026, in force since 30 April 2026, requires sellers to be one of:

• a medical facility (such as a clinic)
• a legal premises that makes or sells drugs and herbal products
• a certified traditional (folk) healer

Existing licences remain valid until they expire, but renewals must meet the new criteria, so roadside shops that are not clinics or pharmacies will gradually disappear. Business owners can read how to open a cannabis shop in 2026.

Step 3: Check the staff, the prescription and the shopfront

A compliant outlet should show these signs:

• DTAM-trained staff on duty during all opening hours (2026 regulation)
• A prescription from a licensed practitioner on form Phor Tor 33 (ภ.ท.33); the prescriber must be treating their own patient, and the supply is capped at 30 days (2025 announcement; Khaosod)
• An effective odour and smoke removal system, with flowers not stored directly on the floor
• No commercial advertising on any channel
• No sales online, through vending machines or over computer networks
• No sales for smoking on the premises, except by practitioners treating their own patients
• No sales at temples, dormitories, public parks, zoos or amusement parks

Caveat: Appearing on MC-GIS does not prove a shop follows every rule. In June 2026 officials started legal action against licensed Bangkok shops that breached their licence conditions. Rules are still changing while the Cannabis Control Act is pending; if in doubt, check directly with DTAM.

Checklist: legal outlet vs red flag

What buyers risk at unlicensed shops

• No traceable source. Licensed sellers must buy from farms certified for good cultivation and harvesting and keep records of source and quantity; illegal shops have no such system.
• Some products are still narcotics. Extracts above 0.2% THC by weight remain a Category 5 narcotic, and those involved can be arrested under the Narcotics Code.
• More inspections. Officials can inspect, seize and freeze goods, and arrest unlicensed sellers on the spot, with the 2026 regulation extending powers to provincial administration officials, including in Bangkok and Pattaya.
• Users may face fines in future. The draft Cannabis Control Act approved by the Cabinet on 22 Sep 2026 would fine users for misuse (the draft is not yet law).
