The 2026 Rules in One Table

Cannabis Is a Controlled Herb — Not Banned

Cannabis flower is a controlled herb in Thailand, not an unrestricted retail product. Since June 2025, lawful dispensing is tied to medical use and a prescription from an authorised practitioner. Possession and use remain subject to the prescription, the medically necessary quantity, premises rules, nuisance law, and other current restrictions.

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: keep the product with its supporting prescription and stay within the medically necessary amount, which the current framework limits to no more than a 30-day supply.

Consumption: public smoking that causes a nuisance is prohibited. Private-property permission does not override medical, public-health, building, hotel, or nuisance rules.

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.

Stash BKK can arrange an on-site telemedicine assessment with a licensed practitioner. Consultations are typically available during a shop visit, usually take around 10–15 minutes and cost 100 THB. The practitioner must make a genuine medical assessment and issues a prescription only when medically appropriate.

A PT33 may cover no more than a 30-day medically necessary supply. Follow the issuing practitioner's dates, dosage, quantity, and dispensing instructions.

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

Do not rely on a simple “private is legal, public is illegal” slogan. Smoking can still breach medical, nuisance, hotel, lease, building, or premises rules, and a retail dispensary licence alone does not authorise on-site smoking.

Private property is still subject to rules

Your hotel or accommodation — follow the property's smoking policy, lease or host rules, building rules, prescription, and nuisance law. Many Bangkok hotels prohibit smoking of any kind and impose cleaning charges.

A private residence — permission from the owner or host is necessary, but smoke must not create a nuisance and building rules still apply.

Dispensaries — do not assume a customer lounge is a smoking room. Current DTAM guidance describes a narrow medical-facility exception involving a dedicated separate room for medical purposes. Ask the premises directly and do not consume unless the location confirms that it is specifically authorised.

Illegal — public spaces

Streets and sidewalks, public parks, beaches, BTS/MRT stations and trains, taxis and tuk-tuks, hotel lobbies and pool decks, shopping malls, markets, airports, and government buildings are not appropriate places to smoke. A relaxed venue or an ordinary retail dispensary licence is not legal cover.

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

Controlled cannabis flower may be dispensed through licensed shops when the applicable medical and retail requirements are met and an authorised practitioner has issued a PT33. Ask to see the exact product label, available COA, and supporting records in-store.

Edibles

Legality is product-specific. Verify the exact product's registration, formulation, label, THC content, manufacturer, and prescription requirements. Stash BKK stocks Baked Brand products and can show the current label and supporting in-store records; this page does not make a blanket approval claim.

CBD

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

Vapes — illegal

Vapes and e-cigarettes are prohibited in Thailand. Stash BKK does not sell them. Do not infer that another product is lawful merely because it is sold in a dispensary; product-specific records still matter.

Delivery Is Not Permitted

Stash BKK does not deliver cannabis flower. The compliant route we use is an in-person visit to a licensed shop, with any required PT33 issued only after an authorised practitioner's assessment. Do not assume that an advertised delivery service satisfies the current medical, prescription, identity, dispensing, or premises requirements.

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 shortcut. Visitors are subject to the same age, identification, medical-assessment, prescription, and dispensing requirements. A shop may facilitate a telemedicine assessment, but the authorised practitioner may request medical information, decline to prescribe, or determine a different course.

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 medical framework remains in force at this article's update date, but rules and enforcement can change. Check current DTAM and Ministry of Public Health notices rather than treating this page as permanent legal advice.
