Can Tourists Still Get Weed in Thailand? (2026 Guide)

Tourists may be assessed for a Thai PT33 cannabis prescription in 2026. Being 20 or older with a passport is necessary, but it does not guarantee a prescription. An authorised practitioner must make a genuine medical assessment and decide that cannabis is medically appropriate.

That’s the short answer. The longer answer matters too — because the rules changed significantly in June 2025, and a lot of the older advice you’ll see online is stale.

What changed in 2025 (and why old guides are wrong)

When Thailand decriminalised cannabis in June 2022, you could walk into any dispensary, show your passport, and buy. No prescription, no fuss. That made Thailand the most accessible cannabis tourism destination in Asia.

That changed on 27 June 2025. The Thai government reclassified cannabis flower as a controlled herb under the Traditional Thai Medicine (TTM) framework. Recreational sale was tightened: you now need a PT33 prescription issued by a licensed Thai practitioner before buying flower.

Foreign visitors are not automatically excluded from assessment. Stash BKK can facilitate an on-site telemedicine consultation, but the practitioner—not the shop—decides whether to issue the prescription.

How to get a Thai cannabis prescription as a tourist

For the full walkthrough, see how the PT33 prescription works. At Stash BKK, the typical flow is:

1. Walk into any Stash BKK location. No appointment needed. On Nut and Ari are open 24/7, including for late-night arrivals.
2. Show your passport. Confirms you're 20+ and identifies you for the prescription record.
3. Complete a telemedicine assessment with an authorised practitioner. Give accurate information about symptoms, history, medicines, and intended use.
4. Pay the 100 THB consultation fee. If medically appropriate, the practitioner issues a PT33 stating the dosage, days, and total quantity, for no more than a 30-day supply.
5. If prescribed, follow the document. Staff can help identify products that match the practitioner's directions; they do not replace medical advice.

The consultation typically takes around 10–15 minutes, but timing and the medical decision can vary.

Where it’s safe and legal to buy

Stick to licensed retail dispensaries that display their permits and keep the required records. A shop may facilitate contact with an authorised practitioner, but the shop itself does not issue the medical prescription. Buying from a non-licensed vendor sits outside the legal framework and provides no reliable product documentation. If you want the wider context before you go, our complete Bangkok cannabis guide covers the law, neighbourhoods, and etiquette in one place.

The four Stash BKK locations are fully licensed under the DTAM framework:

• On Nut — Sukhumvit Soi 50, near On Nut BTS. Open 24 hours.
• Ari — Phahon Yothin / Ari neighborhood, near Ari BTS. Open 24 hours.
• Chinatown / Yaowarat — Yaowarat district, with rooftop bar and city views. Open 2 PM – 2 AM.
• Ekkamai — Sukhumvit 63, near Ekkamai BTS. Open 24 hours.

What’s legal to do with cannabis once you’ve bought it

Do not reduce the use rules to “private-only.” Public smoking can trigger nuisance enforcement, while private property remains subject to the prescription, owner permission, hotel and building policies, and nuisance law. A dispensary retail licence alone does not authorise on-site smoking.

For tourists specifically, this means:

• Hotels and rentals: get express permission, check building rules, and do not create a nuisance. A private room or balcony is not automatic permission.
• No taking it home: exporting cannabis out of Thailand is strictly illegal, including CBD oils. Do not bring it on departing international flights. Penalties are severe — here’s the detail on bringing cannabis in or out of Thailand.
• Driving: do not drive after consumption. Same impairment rules as alcohol.

What about edibles, CBD, and kratom?

• Edibles: product registration, labelling, dosage, and prescription requirements matter. Ask to see the product label and supporting records; do not rely on a generic “cannabis edible” claim.
• CBD products: requirements are product-specific. Verify the exact form, label, ingredients, THC content, registration, and prescription status rather than relying on a generic “under 0.2%” rule.
• Kratom (Mitragyna speciosa): legal for customers 20+ under the Kratom Plant Act B.E. 2565. Sold by the gram at all Stash locations. Separate from the cannabis prescription system — no PT33 needed for kratom.

Bangkok cannabis tourism tips for 2026

• Arriving late? Land at Suvarnabhumi or Don Mueang at 2 AM with no hotel check-in until 3 PM? Stash On Nut, Ari, and Ekkamai are all open 24 hours. Drop in, relax in the lounge, meet the team.
• First time? Tell the practitioner your actual experience and follow the prescribed dosage. Budtenders can explain labels and inventory but should not replace clinical advice.
• With friends? Do not share prescribed products. Each patient needs their own assessment, prescription, and dispensed quantity.
• Rooftop visit? The Chinatown location has a rooftop bar with cocktails and city views. The hospitality amenity is not advertised as permission to consume cannabis.
