Thailand’s cannabis retail sector is contracting fast. According to Ministry of Public Health data as of 28 December 2025, reported by The Nation on 1 February 2026, of 8,636 licences expiring in 2025 only 1,339 (15.5%) were renewed. For a customer, the shop in front of you may comply fully with the current medical framework, or it may still be running on assumptions from 2023. This is a checklist of what to look for: displayed licensing, product provenance, how you are advised, hygiene and price transparency. It works whether you are a patient or a visitor.
1. Why this checklist exists now
The framework changed repeatedly and quickly. The milestones that matter for this checklist are below. For the full legal timeline see topic 1330, and for penalties see topic 1295.
- 9 June 2022: cannabis removed from the Category 5 narcotics list. This was not the legalisation of recreational use, and recreational use is not permitted.
- November 2022: cannabis flower (inflorescence) designated a controlled herb by a Ministry of Public Health notification (B.E. 2565, dated 11 November 2022).
- 26 June 2025: the Notification of the Ministry of Public Health Re: Controlled Herbs (Cannabis) B.E. 2568 replaced the 2022 notification and tightened the rules. Flower may be dispensed only against a prescription on form PT 33 from an authorised practitioner. Each prescription covers no more than 30 days and cannot be refilled, and sold flower must come from a GACP-certified cultivation site.
- Early 2026: press reports describe a new requirement for dispensaries to have a licensed practitioner on site (The Nation, 1 February 2026). The official instrument and its date of effect should be checked against the current regulations.
- April 2026: two Ministerial Regulations B.E. 2569 tightened licensing. The regulation on cannabis/hemp extracts came into force on 26 April 2026, and the controlled-herb licences regulation (No. 2) on 30 April 2026. Neither changes the PT 33 prescription rules. Press reports describe permitted premises as limited to medical facilities, pharmacies, herbal product retailers and traditional healers’ workplaces (Thaiger, 14 August 2026).
Current status: the Cannabis Control Act is still a draft. Cabinet approved it on 22 September 2026 and sent it to the House. When it passes, parts of this checklist may change.
The consequence in numbers: of 8,636 licences that expired during 2025, 1,339 were renewed (15.5%) and 7,297 were not. On 28 December 2025 there were 18,433 registered shops nationwide. Subtracting the 7,297 non-renewals leaves about 11,136 still operating (Ministry of Public Health data, reported by The Nation, 1 February 2026). A later report gives slightly different totals: 18,517 registered, 7,131 closed in 2025 and 11,386 operating (Khaosod English, 22 April 2026).
The practical implication for a customer: you can no longer assume a shop is compliant. Compliance is now something that sets shops apart. A shop that has survived this has done something the majority did not.
2. The checklist
2.1 Licensing: displayed and current
Look for the licence. A compliant operation displays its licensing. Check that:
- It is displayed, not “in the office”.
- The name on the licence matches the business you are standing in.
- The expiry date has not passed. Expiry without renewal is what took 7,297 licences out of the sector, so this is not a pedantic check.
If nothing is displayed, that is your answer. You do not need to interrogate anyone.
2.2 The on-site practitioner
Press reports from early 2026 describe a requirement for dispensaries to have a licensed practitioner on site (The Nation, 1 February 2026). Under the B.E. 2568 notification, a PT 33 may be issued only by authorised practitioners as defined in the notification.
What to check:
- Is there a practitioner present now, not “usually” or “in the mornings”?
- Can you identify them, with a name and a displayed credential?
- Does the person actually advising you have a clinical role, or are they retail staff?
This is the requirement that reshaped the sector. How a shop meets it tells you a great deal about how seriously it takes the rest.
2.3 Product provenance
Ask where the flower came from. A compliant medical supply chain means documented cultivation: a GACP-certified source, batch records and traceability.
What a good answer looks like: a named farm or supplier, a batch or lot identifier on the packaging, and a willingness to show you the documentation.
What a bad answer looks like: “from the north”, a shrug, or irritation at being asked.
Test results. For a medical product, the relevant document is a laboratory analysis. It should cover cannabinoid content and contaminants: pesticides, heavy metals and microbiological content. A wide range of fungi can colonise cannabis flower, several genera produce mycotoxins, and pulmonary aspergillosis has been reported in cannabis users with compromised immunity (see topics 28 and 1245 on Botrytis and mould). For an immunocompromised patient this is a safety question, not a quality one.
Ask to see a certificate of analysis. A shop that has one and shows it to you is operating differently from one that does not. Topic 1318 explains how to read a COA.
2.4 How you are advised
This is the least tangible criterion and often the most revealing.
Good signs:
- Questions before recommendations: what condition you have, what you have tried, what other medication you are taking.
- Willingness to say a product is not suitable, or that you should see a doctor.
- Clear explanation of what is known and unknown about a product’s effects.
- No pressure to buy more than you came for.
Warning signs:
- Medical claims made confidently and without qualification. Cannabis is not an established treatment for most of what it gets claimed for. A shop assistant who says otherwise is either uninformed or selling.
- No questions asked at all.
- Recommendations based on THC percentage alone.
- Any suggestion that you can work around the prescription requirement.
On that last point: under the B.E. 2568 notification, flower may be dispensed only against a valid PT 33 prescription from an authorised practitioner. A shop offering to work around that is selling outside the notification and putting you at legal risk for the sake of its sale.
2.5 Hygiene and storage
These checks are simple and often neglected:
- Sealed, labelled containers, not open jars on a counter.
- Labels carrying product name, batch, date and cannabinoid content.
- Protection from light and heat. In this climate, product stored in a sunlit window is degrading in front of you.
- Clean handling: utensils, gloves, no bare hands in product.
- Look and smell. Visible mould is disqualifying, and so is a musty or ammonia smell. Do not accept visibly mouldy material, and remember that heating does not remove mycotoxins (see topics 28 and 1245).
2.6 Price transparency
- Prices displayed per unit, before you ask.
- Consistent prices: the same product at the same price for everyone.
- An itemised receipt.
A note on tourist pricing. Charging foreigners more is common in many retail settings in the region. In a medical dispensing setting it is a compliance and record-keeping question as much as a fairness one, because a business keeping proper records has a price list.
2.7 Records
Under a medical framework the shop keeps records of the patient, prescription, product, quantity and date.
What you should see: your prescription actually being checked and recorded, and your purchase recorded against it.
What should concern you: a sale with no record made. If the shop is not recording it, either the sale is not compliant or the records are not real.
3. A quick scoring approach
If you want something usable at the door:
| Check | Weight |
|---|---|
| Licence displayed, current, matching name | Disqualifying if absent |
| Practitioner present and identifiable | Disqualifying if absent |
| Prescription checked and recorded | Disqualifying if absent |
| Product provenance answerable | High |
| Certificate of analysis available | High |
| Sealed, labelled, properly stored product | High |
| Advice that asks before recommending | Medium |
| Price displayed, receipt given | Medium |
| Premises clean and orderly | Medium |
Three disqualifying items. If any of the first three fails, the rest does not matter. You are in a shop operating outside the current framework, and you share the risk of that with the shop.
4. If you are assessing a shop as an acquisition
The checklist above is a starting point for due diligence, not a substitute for it. Licence transferability, renewal dates, the practitioner arrangement and ownership rules need a Thai lawyer before you do anything else. These questions are covered in a separate article on investing in a Thai growshop or dispensary.
5. What this checklist is not
It is not a review of any specific shop. This checklist does not name shops; for member reports on named shops, see topic 816. Reviews go stale, but criteria do not.
It is not legal advice, and it is not a substitute for the rules themselves. It is a set of observable signs of compliance, and those signs can mislead in both directions. A shop can display everything and still be cutting corners, and a good operator can have a bad day.
It is not a guide to buying without a prescription. Under the current framework, buying flower requires a prescription. A shop willing to sell without one is not a shop you should be evaluating on hygiene.
6. A note on the wider picture
It is worth saying plainly that the sector’s contraction has costs beyond the businesses that closed. Thousands of people invested in premises, fit-out and staff under one framework and lost them under another.
For a customer, the practical effect is simple: the shops that remain have had to meet a standard the previous group did not, and this checklist is largely a way of confirming that they actually did.
What are people actually finding at the counter now? The formal rules are documented, but how consistently they are applied on the ground is not, and that is exactly what a regional forum can observe. Are prescriptions being checked? Are practitioners present? Are certificates of analysis available on request? Share general observations below, and post reports on named shops in topic 816.

This article is general consumer information, not legal or medical advice. Thailand’s cannabis framework has changed repeatedly. The Cannabis Control Act is still a draft (Cabinet approved 22 September 2026, sent to the House) and may change the rules described here, so check the current position before relying on anything in this article. Under the Notification of the Ministry of Public Health Re: Controlled Herbs (Cannabis) B.E. 2568, flower may be dispensed only against a valid PT 33 prescription. Bringing cannabis into or out of Thailand, including from countries where it is legally prescribed, is treated as drug trafficking under Thai law.
