Current Status
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. Since 30 April 2026, new and renewed shop licences must also be anchored to a qualifying medical, pharmacy, herbal-product or similar credential (details below).
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.

Buying
Who Can Buy, and the PT33 Prescription
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.

2026 Licensing & Enforcement
What Changed for Shops in 2026
Since this page was first published, three regulatory events reshaped who may sell cannabis flower in Thailand and what happens to a seller that breaks the rules. None of them changed the buyer-side basics — 20+, ID, PT33 — but together they explain why there are far fewer shops than in 2024. Everything below is as of 13 September 2026; the fuller narrative is in Thailand's cannabis situation in 2026.
Ministerial Regulation No. 2 B.E. 2569 on controlled herbs — effective 30 April 2026
The single biggest change of the year. Under the regulation published and in force on 30 April 2026, a new application to sell cannabis flower is entertained only when the premises already hold an anchor credential: a hospital or clinic licence, a pharmacy or drug licence, a registered herbal-product licence, a cannabis-extract licence, certified folk-healer status, or a certified cultivation site. A shop that is nothing but a retail counter no longer fits the licence model.
Renewals must meet the same criteria plus dedicated secure storage, odour control and trained staff present throughout opening hours. Licences issued under the older 2020–2021 rules remain valid only until their own expiry, with 31 December 2026 widely reported as the cut-off for old-framework paperwork. Thousands of shops closed across the 2025–2026 renewal cycle; only a minority of expiring licences were renewed.
Extract regulation — effective 26 April 2026
A separate regulation on cannabis and hemp extracts took effect on 26 April 2026, restricting high-THC extracts to a short list of permitted purposes and licence holders. It does not change the rules for flower, but it is one more reason hash, rosin and other concentrates sit outside what a retail dispensary can lawfully sell.
DTAM enforcement guidelines — 22 June 2026
On 22 June 2026 DTAM published graduated enforcement guidelines for licensed sellers. Suspensions apply to record-keeping, licence-display and advertising failures, with longer suspensions for dispensing without a prescription. Revocation applies to the serious categories: selling to anyone under 20, selling online or by vending machine, and allowing cannabis smoking on the premises. Repeat breaches escalate, and a suspension on record counts against the shop at its next renewal. See also the penalties section.
Draft Cannabis and Hemp Act — not passed as of September 2026
Despite headlines claiming Thailand "passed a new cannabis law", it has not. The draft Cannabis and Hemp Act went to public consultation from 22 April to 21 May 2026, cleared only a first reading, and missed the mid-year parliamentary session. A rival, stricter bill was filed in July 2026, and nothing is expected before early 2027. Until an Act passes, the June 2025 controlled-herb notification plus the two 2026 ministerial regulations remain the operating law, and every other section of this page is written against them.
What it means for a buyer: a shopfront is not a licence. Look for the licence display and the prescription step, and treat a shop that skips either as one that may not be licensed at all.

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.

Products
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
CBD
Products under 0.2% THC sit in a lighter regulatory framework than flower.
Vapes — illegal

Delivery Is Not Permitted
Stash BKK does not deliver any product; every transaction is walk-in only. 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.
Borders
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.

Visitors
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.

Inside Thailand
Licensed sellers — since 22 June 2026
DTAM's graduated enforcement guidelines, published on 22 June 2026, set written penalties for licence holders: suspensions for record-keeping, licence-display and advertising failures, longer suspensions for dispensing without a prescription, and revocation for selling to anyone under 20, selling online or by vending machine, or allowing cannabis smoking on the premises. Repeat breaches escalate, and a suspension on record counts against the shop at its next renewal. Details in the 2026 licensi
