Dispensary-to-Clinic Conversion Guide (2026)

If you hold a cannabis retail license in Thailand, the shop model you opened under is being phased out. Under a policy announced in early April 2026, the Ministry of Public Health will require the roughly 11,000 remaining licensed cannabis shops to convert into regulated medical establishments — a clinic, a pharmacy, or a traditional-medicine pharmacy, each with an on-site licensed practitioner. Shops that do not convert must stop selling cannabis flower.

This guide explains the mandate, what a converted clinic must have, rough costs, and the three-year clock that is already running against your license-expiry date.

The short answer

You have three realistic paths:

1. Convert your business into a licensed medical establishment with an on-site practitioner and the required facility standards.
2. Pivot to a model that does not require a cannabis-flower license — for example, sub-0.2% THC CBD retail under food, cosmetic, or herbal-product rules.
3. Wind down before your license expires, on your own terms rather than at an enforcement inspection.

Doing nothing is the same as choosing option three, just later and with more risk. Renewal is no longer a formality — it is a full re-qualification under the clinic-standard rules described below.

What the April 2026 mandate actually says

The mandate is a policy direction backed by the ministerial regulations that landed across 2025 and 2026. The key points, as reported by primary Thai media and law-firm analysis:

• The ~11,000 shops still operating must become regulated medical establishments — clinic, pharmacy, or traditional-medicine pharmacy — each with an on-site licensed practitioner able to dispense cannabis.
• Sales are limited to patients holding a valid prescription, capped at a 30-day supply.
• No advertising and no recreational sales.
• Cannabis flower must be sourced from GACP-certified farms (Good Agricultural and Collection Practices).
• Authorities will map licensed outlets and issue identification stickers showing license status and expiry, to make inspection faster.
• The Department of Thai Traditional and Alternative Medicine (DTAM) has stood up training programmes and e-learning to help operators and staff qualify.

Thai officials have publicly estimated that only about 15% of the original ~18,000 shops — roughly 3,000 outlets — will complete the transition. Treat that as a warning about how demanding the standards are, not as a fixed cap.

The three-year clock — and why yours may be shorter

Officials have described a transition of up to three years to convert, aligned to license-expiry cycles rather than one nationwide deadline. In practice this means your real clock is your own license expiry date, because every renewal is now assessed against the new clinic-standard rules.

If your license expires in 2026, your effective window is months, not years. Bangkok Post has reported that a large batch of cannabis distribution licenses valid for 2026–2028 was approved, with about half set to expire in 2026 — which points to a second attrition wave this year. Confirm your own expiry date with the issuing authority and plan backward from it.

What a converted clinic must have

A converted establishment has to satisfy both the medical-facility requirements and the cannabis-flower licensing criteria under Ministerial Regulation No. 2 B.E. 2569 (published in the Royal Gazette on 30 April 2026). At a minimum:

On-site licensed practitioner

A practitioner qualified to dispense cannabis must be physically present throughout all operating hours. Gaps in coverage are grounds for non-renewal. See our staffing requirements guide for who qualifies and how the hours rule is enforced.

Prescription-only dispensing

Every transaction must be tied to a valid prescription (PT 33), with a maximum 30-day supply per patient. Recreational sales and walk-up sales without a prescription are prohibited. The prescription system is covered in our PT 33 guide.

Qualifying applicant status

The operator must anchor to the health sector — for example a hospital license, a herbal-product manufacturing or sales license, a pharmaceutical license, a Category 5 extract license, folk-healer certification, or a GACP cultivation site supplying licensed buyers. The standalone open-market dispensary no longer qualifies on its own. Details are in our cannabis license guide.

Facility standards

• Segregated, climate-controlled storage — cannabis flower stored separately, elevated off the floor, protected from sunlight, with temperature and humidity control.
• Odor and smoke elimination system — typically activated-carbon filtration or sealed extraction, with documented maintenance.
• Premises rights — ownership or possessory rights, or written owner consent if you are not the owner.
• Record-keeping — monthly source, usage, and inventory reports to DTAM via forms Phor.Tor. 27, 28, and 29.

GACP-sourced supply

Cannabis flower must come from GACP-certified farms. If you currently buy from unverified suppliers, securing a compliant supply chain is one of the first things to fix.

Rough conversion costs

The figures below are planning estimates, not quotes. Fee schedules in particular are unresolved: commonly-cited business-type license fees conflict with the statutory schedule under the Herbal Products Act B.E. 2562. Treat every THB figure as “reported — confirm with the issuing authority (DTAM / Thai FDA).”

The practitioner salary and the facility upgrades are what close most shops — not the license fee itself.

Step-by-step: how to convert

1. Confirm your license expiry date with the issuing authority. This is your real deadline.
2. Get legal advice specific to your premises, license type, and location before spending money.
3. Choose your target model — clinic, pharmacy, or traditional-medicine pharmacy — and confirm which qualifying credential you will anchor to.
4. Recruit a licensed practitioner who holds DTAM cannabis-prescribing certification and can cover all operating hours.
5. Bring the facility up to standard — storage segregation and climate control, odor and smoke elimination, premises documentation.
6. Secure GACP-certified supply and obtain Certificates of Analysis for your products.
7. Install compliant record-keeping and start logging PT 33 transactions and monthly DTAM reports before you reopen under the new model.
8. Submit your application or renewal under the current rules, with complete documentation to avoid remediation delays.
9. Enroll staff in DTAM training / e-learning so coverage never lapses.

What happens if you do nothing

Operating after license expiry is unlicensed activity with no grace period. Selling cannabis without a valid prescription can carry up to one year’s imprisonment and/or a THB 20,000 fine under the Traditional Medicine Act B.E. 2542, plus administrative suspension, closure, and revocation. A license previously suspended for non-compliance cannot be renewed. The full penalty picture is in our cannabis law overview.

Where to get help

• Review the medical-side requirements your clinic must meet in our medical cannabis section.
• Find already-converted operators for benchmarking in the clinic directory.
• Work through the full compliance checklist before your inspection.
• Start from the top with the cannabis business hub.
