The 2026 Rules in One Table

Cannabis Is a Controlled Herb — Not Banned

Cannabis is not banned in Thailand. As of 2026 it remains legal to buy, possess, and consume privately. On 27 June 2025, cannabis flower was reclassified as a controlled herb under the Traditional Thai Medicine (TTM) system, which added a prescription requirement to flower purchases — a tighter framework than the wide-open 2022–2024 era, but a prescription-based system, not a prohibition.

What the controlled-herb framework means in practice:

Sales: cannabis flower is legal to sell only at licensed dispensaries, only with a PT33 prescription on file for each customer.

Possession: legal for prescription-holders within reasonable personal amounts. Keep your prescription with the product when carrying it.

Consumption: private consumption is legal; public consumption is illegal — a rule that has been consistent since 2022.

Cultivation: restricted compared to 2022–2024; commercial growers need licensing.

Who Can Buy, and the PT33 Prescription

To legally buy cannabis flower in Thailand in 2026 you need two things: to be 20 or older with a valid ID or passport, and a PT33 prescription issued by a licensed practitioner. The PT33 requirement has applied to all flower purchases since June 2025 — it's the gate every legal flower sale passes through.

The prescription is procedural, not a barrier. Major dispensaries arrange it on-site via telemedicine: a short video consultation with a licensed practitioner, done at the shop, the same hour you arrive. At Stash BKK it takes around 10–15 minutes and costs 100 THB, handled through our DTAM-endorsed telemedicine platform. No separate clinic visit, no appointment, no prior Thai medical record.

A PT33 is valid for 30 days from the date of issue and can be used at the issuing dispensary or any other licensed dispensary during that period.

Buying without a prescription is only possible outside the legal framework — from unlicensed sellers who can't issue one, which carries real legal risk and gives you no documentation or quality information.

Where You Can and Cannot Consume

The single rule that governs consumption in Thailand: private is legal, public is illegal. This has been the rule since decriminalisation in June 2022 and did not change with the June 2025 reclassification.

Legal — private spaces

Your hotel room — if the hotel allows smoking. Many Bangkok hotels prohibit smoking of any kind and charge internal cleaning fines of 5,000–10,000 THB when smoke is detected; that's hotel policy, separate from Thai law. Edibles avoid the issue entirely.

A private residence — your apartment, an Airbnb (subject to the host's and building's rules), or a friend's place with permission.

Licensed dispensary lounges — consumption on licensed premises is treated as private. All four Stash BKK locations have on-site lounges.

Illegal — public spaces

Streets and sidewalks, public parks, beaches, BTS/MRT stations and trains, taxis and tuk-tuks, restaurants, bars and clubs (even cannabis-friendly ones), hotel lobbies and pool decks, balconies overlooking public space, shopping malls, markets, airports, and government buildings. A relaxed venue is not legal cover — only licensed dispensary premises are the exception.

Penalties for public consumption

Fines up to 25,000 THB (about 700 USD as of 2026) and/or up to 3 months imprisonment in serious cases. For tourists this usually means a fine and confiscation rather than jail, but it depends on circumstances. Driving under the influence is treated as DUI, with serious consequences.

What's Legal to Sell: Flower, Edibles, CBD — Not Vapes

Flower and pre-rolls

Legal at licensed dispensaries with a PT33 prescription. Compliant shops sell lab-tested flower with a Certificate of Analysis (COA), sourced from GACP-licensed farms.

Edibles

Legal when Thai-FDA-approved. Stash BKK stocks Baked Brand microdose cookies and caramels (up to 1.6mg THC), which are Thai-FDA-approved products. Edibles are the practical answer to strict no-smoking hotels: no smoke, no smell. The same consumption rule applies — private spaces only.

CBD

Products under 0.2% THC sit in a lighter regulatory framework than flower.

Vapes — illegal

Vapes and e-cigarettes are illegal in Thailand entirely. No licensed dispensary sells them; shops offering vapes — like those selling hash or untested product — are operating outside the rules. The legal dispensary menu is flower, pre-rolls, and Thai-FDA-approved edibles.

Delivery Is Not Permitted

Cannabis delivery is not permitted under Thailand's current medical framework, even though plenty of Bangkok shops and apps advertise it. Legal flower runs through prescription-based, in-person dispensing at a licensed premises — handing a bag to a rider skips the step the whole framework is built on. A shop willing to run delivery outside the rules is a shop cutting compliance corners; the compliant route is walking into a licensed dispensary, where the PT33 is handled on-site.

Import and Export Are Strictly Illegal

Do not move cannabis across an international border, in either direction. Exporting cannabis without explicit government permission is illegal — flower, edibles, seeds, or any part of the plant, including cannabis-derived CBD products — regardless of where you bought it or how small the amount. Your destination country's import laws apply on top, and many still treat any amount as a criminal offence. Mailing it home is still exporting it.

The same applies in reverse: importing cannabis into Thailand without a permit is illegal, even from countries where you bought it legally. There's no reason to — the legal market is on the other side of customs.

Domestic travel within Thailand is different: cannabis is legal nationwide, and small personal amounts bought legally haven't been a domestic enforcement focus. Airline and airport policies vary, though — the zero-friction option is to buy again at your destination.

Kratom: Legal Under Its Own Separate Law

Kratom (Mitragyna speciosa) is legal in Thailand — but under a completely separate framework from cannabis. It was legalised in 2021 after decades of prohibition and is regulated under the Kratom Plant Act B.E. 2565. No PT33 prescription is required: kratom is sold directly at licensed shops to adults 20 and older. It is not THC and not CBD, and nothing in the cannabis framework applies to it.

Tourists: Same Rules as Everyone Else

There is no separate tourist regime. Visitors can legally buy cannabis under exactly the same conditions as residents: 20 or older, valid passport, Thai PT33 prescription for flower. No prior Thai medical record or local doctor is required — dispensaries arrange the prescription on-site.

Foreign medical cannabis cards are not valid in Thailand. Thailand only recognises prescriptions issued under its own PT33 framework by licensed Thai practitioners — you'll need a Thai prescription regardless of what you hold at home.

And the rules that catch tourists most often: consume in private only, and never attempt to fly home with anything you bought here.

Penalties: What Breaking the Rules Actually Costs

Inside Thailand

Cannabis flower is a controlled herb under the Thai Traditional Medicine framework, and the penalties sit on the seller: selling outside the prescription rules carries up to 1 year imprisonment or a 20,000 THB fine, with steeper penalties proposed. On the buyer side, the framework only protects purchases made through it — a legal purchase requires a PT33 on file, and buying without one means operating outside the framework, with real legal exposure and no documentation if anything goes wrong. Public consumption carries its own penalty, covered in the consumption section above: up to 25,000 THB and up to 3 months.

At the border — and beyond

Exporting cannabis without a permit is illegal, and since 17 June 2026 the Thai side has hard numbers: forfeiture of the goods plus a 30,000 THB fine per kilogram, with exposure under the Customs Act of up to 10 years' imprisonment and/or fines up to four times the value of the goods. Enforcement is not theoretical — joint Thai-UK operations (Operation Chaophraya) have run since 2024, airport screening has been stepped up, and between October 2025 and June 2026 authorities logged 3,309 smuggling cases and seized over 37 tonnes.

If you make it out — you probably won't — the destination country takes over:

• UK: importation of a Class B drug — up to 14 years and/or an unlimited fine. Couriers caught arriving by air went from 142 in 2023 to 976 in 2025.
• Singapore: importing over 500 g of cannabis is punishable by death; 330–500 g means 20–30 years or life plus caning. A man was executed in April 2026 for importing roughly 1 kg.
• Malaysia: trafficking is punishable by death (discretionary since 2023) or life imprisonment plus caning; 200 g or more creates a presumption of trafficking.
• Indonesia: up to life imprisonment or the death penalty for trafficking; foreigners are on death row for cannabis offences.
• Japan: importation carries up to 7 years, or 10 if for profit.
• UAE: trafficking carries 10 years to life, with the death penalty available in aggravated cases.

Rule Changes Since 2022

1. June 2022

   Thailand becomes the first Southeast Asian country to decriminalise cannabis, removing it from the Category 5 narcotics schedule. The open dispensary era begins.

2. 2022 – 2024

   Dispensaries open across Bangkok, Chiang Mai, and Phuket under a "recreational by default" market. The regulatory framework lags behind reality.

3. Mid-2025

   A political shift brings public debate on full re-criminalisation versus a medical-only framework. Full re-criminalisation is rejected; a prescription-based compromise is chosen instead.

4. 27 June 2025

   Cannabis flower is reclassified as a controlled herb under Traditional Thai Medicine. The PT33 prescription requirement begins for flower purchases. Licensed dispensaries continue operating under the new rules.

5. 2026 (current)

   The system is stable. Dispensaries have adapted, prescriptions are arranged on-site at low cost, and no major changes are signalled for 2026.
