Quick answer: how do you choose a dispensary in Bangkok?

Check ten things before you walk in: whether the shop holds a license, whether a licensed practitioner is available, how products are tested and traced, whether the staff know the products and speak English, whether the space is clean, whether prices are posted, what ID is required, how easy it is to reach by BTS or MRT, what the opening hours are, and how the shop treats the medical rules. A shop that is vague about any of these is giving you information.

This guide is a checklist, not a ranking. It applies to any shop in the city, including ours.

Key facts

1. Does the shop hold a license, and can it show you?

This comes first because it decides whether the rest matters. Since 30 April 2026, a new or renewed flower license requires the applicant to hold a qualifying license, such as a healthcare facility, pharmacy or herbal product license. Licenses issued earlier stay valid until they expire. Failing to display a license is itself a suspendable breach under the guidelines reported on 22 June 2026.

Ask to see it, and look for it on the wall. The Department of Thai Traditional and Alternative Medicine also runs a public map, the Medical Cannabis Geographic Information System, where you can search for an outlet and check its status. An entry can carry the company name rather than the shop sign, so zoom in on the street if a trade name finds nothing. Our explainer on whether weed is legal in Bangkok walks through these rules with sources and dates.

2. Is a licensed practitioner available?

A purchase of flower needs a prescription, and only a licensed practitioner can issue one. The notification lists seven professions, including doctors, Thai traditional medicine practitioners, folk healers, Chinese medicine practitioners, pharmacists and dentists. A shop that tells you no paperwork is needed is working outside the rule.

So ask a direct question: who writes the prescription here, and can I speak to them today? A clear answer is a good sign. A shrug is not. If you want to understand the form first, read how a Thai prescription is issued. A prescription issued in another country is not valid in Thailand.

3. Can the shop explain where its products come from and how they were tested?

Traceability is a fair question for any retailer. Ask which licensed grower or supplier a product came from, and whether there is a lab report, often called a certificate of analysis, that you can read. A report that lists cannabinoid content and testing for contaminants is more useful than a general promise of quality.

Staff do not need to recite chemistry. They do need to answer plainly, or say they will find out. If a shop cannot say where a product came from, treat that as a gap.

4. Do the staff know the products and speak your language?

The April 2026 regulation requires at least one DTAM-trained staff member on the premises during opening hours. Beyond that minimum, you want people who ask about your situation before they hand you anything, explain the rules in plain English, and are comfortable saying “I don’t know, let me check.”

Test it. Ask one simple question about what a product contains and see whether the answer is specific. Good staff do not rush you, and they do not push whatever is most expensive.

5. Is the shop clean and set up for storage?

You can judge this in thirty seconds. Look for a tidy floor and counter, products stored away from direct sun, and a space that does not smell musty. The regulation published on 30 April 2026 also asks licensed premises to store flower separately, off the floor, with an effective odor and smoke removal system. A shop that looks careless about storage probably is.

6. Are the prices clear?

You should know what you will pay before you commit to anything. Look for posted pricing, and ask whether the price changes depending on who you are. A fair shop gives a visitor the same price as a resident and tells you the total before it rings you up. We do not quote prices in articles, so check them in the shop or ask when you call.

7. What ID does the shop ask for?

A compliant shop checks ID, because the minimum age is 20 and sales to anyone under that, or to pregnant or breastfeeding women, are prohibited. Bring your passport or a photo ID. Be wary of any shop that waves you through without looking. That tells you how it handles the other rules too.

8. Is it medical or adult use, and does the shop say so honestly?

Thai rules treat sales as medical use, with a prescription. A shop that describes itself as recreational, markets a “party” angle, or promises effects is not describing the legal position accurately. Look for plain, factual language about the medical framework and no health promises. Cannabis smoke and smell are treated as a nuisance under the Public Health Act, so a good shop will also tell you where you cannot consume.

9. How easy is it to reach?

For a visitor, the transit stop matters. All four Siam Green Co branches in Bangkok are walkable from a BTS or MRT station, and the Google Maps listing for each is the quickest way to get there:

10. What are the opening hours?

Treat hours as a plain fact and confirm them on the shop’s Google listing, since they can change. Phrom Phong, Silom and Nana are open daily from 11am to 3am. Chinatown is open daily from 8am to midnight. The all-branch page lists each address, phone number and the hours in one place.

Frequently asked questions

Which dispensary in Bangkok is right for me?

The one that passes your checklist and is close to where you are staying. Start with the license, a practitioner on hand, honest answers about testing, and ID checks. Then pick by location: Sukhumvit has Phrom Phong and Nana, the business district has Silom, and the old city has Chinatown. We make no claim that any one shop is better than another.

Do I need a prescription to purchase cannabis in Bangkok?

Yes. Since 26 June 2025, flower is dispensed against a prescription from a licensed practitioner, for up to 30 days of supply. CBD products under 0.2 percent THC are the exception. A practitioner is available at each Siam Green Co branch.

What do I need to bring?

Your passport or photo ID. You must be 20 or older. A prescription from another country is not valid in Thailand.

Is the shop I found in an old video still open?

Maybe not. Many shops closed after failing to renew their licenses in 2025. Check the current Google Maps listing and the opening hours before you travel, or call the shop.

How do I check that a shop is legitimate?

Look for a displayed license, ask who issues the prescription, ask about testing, and search for the outlet on the Department of Thai Traditional and Alternative Medicine’s public map. A shop that is open about all four is behaving the way the rules intend.

Can I use cannabis in public or take it home?

No to both. Cannabis smoke and smell in public are treated as a nuisance, and ignoring an official order to stop can bring up to three months in prison, a fine of up to twenty-five thousand baht, or both. Taking cannabis out of Thailand is an export offense with up to ten years in prison.

Pick the branch nearest your hotel, then open it in Google Maps or call before you set out: Phrom Phong, Silom, Nana or Chinatown. More about the company is on the Siam Green Co homepage. Also available on Koh Samui: Chaweng.
