Living in Thailand: Cannabis Goes Medical-Only

Bangkok — For anyone living in Thailand since 2022, the green-leaf shopfront has become as ordinary as a 7-Eleven. On Tuesday the government moved to make it history. Public Health Minister Pattana Promphat announced that Cabinet had approved a new cannabis control bill that treats the plant as medicine only, licenses every stage from farm to sale, and gives existing dispensaries a hard deadline: convert into a licensed clinic with a medical practitioner, or close.

It is not the dramatic "back on the narcotics list" reversal some headlines imply. It is slower and, for long-stay foreigners, more practical than that. Here is what the bill does, what is already enforceable, and where expats tend to get caught out.

What the Cabinet actually approved

The bill builds a single licensing system around cannabis. Farms of every size must register their location and output. Growing, processing, importing, exporting and selling all need a licence, generally valid for three years. A national cannabis committee chaired by the Public Health Minister sits on top, and penalties are described as "clearer and heavier" than today's.

The shop-closure timeline for Bangkok, Phuket and Chiang Mai

More than 10,000 cannabis outlets and grow sites are registered nationally, and the ministry says over 95% are now in its digital database. Their three-year licences expire in waves: roughly 5,000–6,000 this year, another 4,000–5,000 in 2027, and about 1,000 running into 2028.

So the Bangkok expat on Sukhumvit, the Phuket digital nomad in Patong and anyone enjoying Chiang Mai living near Tha Phae Gate will see shop numbers thin gradually, not overnight. Expect the survivors to look more like pharmacies — a practitioner on site, a prescription on file, and a 30-gram, 30-day cap per patient.

The catch nobody mentions: the rules already apply

Flower sales have required a medical prescription since mid-2025. In June 2026 the ministry admitted it had found forged medical certificates and pre-signed Phor Thor 33 prescription forms being used to sell to walk-in customers. Prescription codes are now checked digitally against the issuing practitioner and clinic, and duplicates get flagged.

What that means for you: a "consultation" that takes thirty seconds at the counter is not a medical prescription, and if the paperwork behind your purchase is fake, you are the one holding product without a legal basis. Inspection teams are being sent specifically to tourist provinces and big cities.

Why it matters more if you hold a Thai visa

A tourist who gets a fine goes home. A foreigner living in Thailand on a retirement, marriage or DTV visa Thailand stamp has far more to lose. Thailand's unified deportation regulation took effect on 28 August and gives the authorities wide discretion over foreigners whose conduct is judged contrary to public order. We covered it in Thai visa holders face new deportation rules. A drug case, even a small one, is the kind of record that can surface at your next extension.

Do not carry it home, or anywhere else

The same week as the Cabinet vote, a UK court sentenced four couriers over 460 kilograms of Thai cannabis packed into 22 suitcases. UK arrests of air passengers carrying Thai cannabis rose again in 2025 and surged in the first half of 2026. The point for residents is simple: Thai rules end at the departure gate. Taking cannabis, edibles or oils out of Thailand is trafficking under almost every destination's law, and gangs actively recruit travellers to do it. If a stranger or a "friend of a friend" offers you a free flight with a bag, walk away.

Practical steps for expats this month

If you use cannabis for a real condition, get assessed by a licensed doctor or Thai traditional medicine practitioner and keep the prescription with the product. Buy only from a shop you can find in the ministry's registry, and do not buy more than the prescribed amount. Never use it in or near schools, temples, parks or your condo's shared areas — building juristic offices can and do complain.

If you do not use it, very little changes, except that your street may get quieter. If you are renting in Thailand, it is worth asking what the shop downstairs will become when its licence runs out before you sign a two-year lease. For the wider cost of living in Thailand and Thailand healthcare for foreigners, this bill is a footnote. For your visa file, it is not.
