Thailand's cannabis U-turn — what it means for Phuket

Four years ago, Thailand became the first country in Asia to remove cannabis from its narcotics list. The move was championed by Anutin Charnvirakul and the Bhumjaithai Party, framed as an agricultural and medical opportunity. The idea was that farmers would grow it, clinics would prescribe it, and the traditional medicine sector would benefit.

What actually happened was different. Because the government removed cannabis from the narcotics list before passing a law to regulate it, there was a gap — and the market filled it fast. Cannabis dispensaries opened everywhere. By some counts, over 10,000 shops were operating nationwide within two years. Phuket alone had more than 1,000 at its peak. Bangla Road, Kata, Rawai, Cherng Talay — green spikey leaves appeared on storefronts across the island.

The regulation never caught up. Recreational use was never explicitly legalised, but it was never explicitly banned either. Tourists bought openly. Residents walked past cannabis cafes on their school run. The gap between official policy (“medical purposes only”) and street-level reality (walk in, buy a joint, walk out) became one of the more absurd regulatory situations in Southeast Asia.

That gap is now closing.

What the cabinet just approved

On 22 September 2026, the Thai cabinet approved a bill that restricts cannabis to medical use only and introduces penalties for recreational sale and possession. The bill now goes to parliament.

The key changes:

Cannabis is classified as a “controlled herb” under traditional medicine law. Not reclassified as a narcotic — that distinction matters — but regulated with real teeth for the first time.

Recreational sale and purchase without a prescription is explicitly prohibited. The ambiguity that allowed dispensaries to operate as de facto recreational shops is being closed.

Public consumption is banned, even with a valid prescription.

Penalties include fines of up to ฿25,000 and up to three months’ imprisonment for unauthorised purchases or public consumption. Selling without a prescription carries up to one year’s imprisonment or a ฿20,000 fine.

Online sales, vending machines, and sales near schools and temples are banned specifically.

What this means if you enjoy a smoke

If you have been buying cannabis from a dispensary without a prescription — which describes the vast majority of customers at Phuket’s cannabis shops — that transaction becomes explicitly illegal once the bill passes parliament.

To purchase legally, you will need a prescription from a licensed Thai practitioner. Prescriptions are capped at 30 days and are single-use. The prescription specifies strain, dosage, and duration. This is not a formality — it is a medical gatekeeping system. That said, for residents who want to go through the process, obtaining a prescription is unlikely to be difficult in practice. Clinics will adapt to the demand.

For tourists, the legal pathway becomes impossible on paper. Obtaining a prescription from a licensed Thai practitioner for a short holiday stay is not a realistic route. Whether that changes what actually happens at street level during high season is another question — and if you have spent any time on Bangla Road, you already know the answer.

The honest assessment: enforcement will determine what this actually looks like on the ground. Thailand has a long history of laws that exist on paper and are enforced selectively. Whether Phuket’s dispensaries close, convert, or simply carry on with a wink depends on provincial enforcement priorities once the bill becomes law. Once the cat is out of the bag, it is hard to get it back in — and more than 1,000 dispensaries on one island is a very large cat.

What this means for the shops

Phuket had 1,089 cannabis shops before a provincial crackdown in August 2026 brought that number down to 1,065. Thirty-five licences were revoked and 112 were suspended in that first enforcement round.

Under the new bill, existing dispensary licences expire in stages through 2028. Any shop that wants to continue operating must convert to a licensed medical facility with a qualified practitioner on site. That is a fundamentally different business model — from retail to clinic.

The most immediate deadline is 31 December 2026, when Category 5 licences issued under the earlier 2020/2021 regulations expire. Holders must re-qualify under the 2026 framework — including premises documentation, dedicated storage, qualified personnel, and DTAM-trained staff. Industry consultants estimate re-qualification takes four to six months, which means if you have not started the process, you are already behind.

The broader Cannabis Control Act has not yet been submitted to parliament. Parliamentary consideration is expected January 2027 at the earliest. No passage date exists — anyone quoting one is guessing. But the direction of travel is not in doubt.

For the owner running a small cannabis shop in a Rawai side street, the cost of employing a licensed practitioner and meeting clinic regulatory requirements is likely prohibitive. The shops that survive will be the ones that can afford the conversion or were already operating as medical dispensaries.

The Ministry of Public Health has flagged tourist provinces — which means Phuket — for priority enforcement inspections.

The bigger picture

Thailand’s cannabis experiment was genuinely significant. It was the first major liberalisation in Asia, and it created an industry from nothing in under two years. More than 10,000 businesses, tens of thousands of jobs, a supply chain from northern growers to southern dispensaries.

Whether the regulatory reversal is a correction of a policy that moved too fast or a conservative backlash against a policy that was working depends on who you ask. What is not in dispute is that the regulatory vacuum of 2022–2025 created a situation that was always going to resolve one way or the other.

It is resolving toward restriction. The bill still needs to pass parliament, so the timeline is not immediate — but the direction is clear.

If you run a shop, the time to talk to a lawyer is now, not when the licence expiry notice arrives. If you are a consumer, the prescription pathway is the one to understand. And if you have been walking past those spikey green leaves on Bangla Road wondering how long they would last — you probably have your answer.

The quick questions

Can I walk around with it? Only if you hold a valid PT33 prescription and are carrying no more than a 30-day supply. Without a prescription, possession has no legal protection.

Can I smoke it in public? No. Public consumption is banned regardless of whether you have a prescription. That includes streets, beaches, parks, markets, BTS and MRT stations, hotel lobbies and pool decks, shopping centres, and government buildings. Penalty: up to ฿25,000 fine and up to three months’ imprisonment.

Can I drive high? No. Driving under the influence of cannabis is treated as DUI with serious consequences. Do not do this.

Can I buy with a prescription and enjoy it at home? Yes — with conditions. You need a valid prescription, and you need permission from the property owner or host. If you are renting, check your lease. If you are in a hotel, check their policy. If you are in a condo, check the building rules. You also cannot create a nuisance for neighbours.

What should I do if someone is smoking in public near me — at the beach, at a cafe? Practically speaking, this is Phuket — you are likely to encounter it regardless of what the law says. Public consumption is illegal and you are within your rights to ask someone to stop or to raise it with the venue. Whether you do is a personal call. If it is at a business you frequent, the business itself carries liability for allowing consumption on the premises — they have more reason to act on it than you do.
