How to get cannabis legally in Thailand (2026): a guide for every region

The legal way to get medical cannabis anywhere in Thailand: who can prescribe a PT33, how to find a licensed clinic outside Bangkok, what changes by region, and what to avoid.

Updated 9 November 2026

Thai cannabis law changes often. This guide is accurate as of 9 November 2026. A new Cannabis and Hemp Act is on its way through Parliament, so check the date before you rely on anything here.

The same law applies in every province

Cannabis rules are set nationally by the Ministry of Public Health, so Chiang Mai, Phuket and Pattaya follow the same law as Bangkok. Since June 2025 cannabis flower has been a "controlled herb": legal for medical use only, sold only against a prescription, to adults aged 20 and over.

What does change from place to place is how many licensed clinics there are, how many staff speak English, and how actively local police check shops. Our regional pages cover that.

Step by step

  1. Find a licensed practitioner. Medical doctors, Thai traditional medicine practitioners and several other licensed professions can prescribe. In tourist areas many dispensaries have one on site; in smaller cities you are more likely to need a clinic or hospital.
  2. Get assessed. The practitioner records your diagnosis and decides whether cannabis is appropriate.
  3. Receive a PT33. This is the official prescription form (ภ.ท.33). It lists your name, passport or ID number, the diagnosis, the daily dose and the total amount, up to 30 days' supply.
  4. Buy in person. Take the PT33 and your passport or Thai ID to a licensed shop. The shop keeps a copy.
  5. Use it privately. Public use can be prosecuted as a nuisance, and hotels and condos can ban smoking altogether.

Finding a clinic outside Bangkok

  • Start with our city pages. Each one lists clinics and dispensaries we could source, and says where the details came from.
  • Check the licence. The government's MC-GIS map at cannabis-gis.dtam.moph.go.th shows licensed shops. A green sign and jars in the window prove nothing.
  • Ask before you go. Message ahead to ask whether a practitioner is on site that day and what the consultation costs.
  • Thai hospitals. Some public hospitals run cannabis or Thai traditional medicine clinics, especially in provincial capitals. Expect fewer English speakers and more paperwork.

Moving around the country

  • Carry your PT33 and receipt whenever you carry cannabis, including between provinces.
  • Buy what you need where you are staying rather than travelling with it. We have not found clear official guidance on carrying prescribed cannabis on domestic flights, so the safest choice is not to.
  • Never cross a border with cannabis. Thailand borders Myanmar, Laos, Cambodia and Malaysia, and all four punish drug offences far more harshly. Exporting cannabis from Thailand can mean up to 10 years in prison.

What to avoid

  • Shops that sell without a prescription, or offer to "write one" without seeing you
  • Online orders, LINE or Telegram sellers, and delivery of any kind, all illegal
  • Edibles and drinks without a Thai FDA number
  • Smoking in public, on beaches, or near temples and schools

CBD and extracts

Products under 0.2% THC are treated more leniently than flower, but CBD food, drinks and cosmetics still need Thai FDA approval. Since 26 April 2026 licensed businesses can make or sell extracts above 0.2% THC for medical purposes only.

What may change next

The cabinet approved a draft Cannabis and Hemp Act on 22 September 2026. It would regulate cannabis from cultivation to sale and require shops to operate as medical facilities. It is not law yet. When it passes, we will update every regional page.
