Is cannabis legal in Thailand in 2025? Thailand has been at the forefront of cannabis reform in Southeast Asia — but in 2025 the landscape is shifting once more. If you’re a tourist or a Thai local wondering Is Cannabis Legal in Thailand in 2025, this guide will walk you through the latest laws, restrictions, and practical tips — and show you how ThaiCannaMed can help you legally obtain a medical cannabis prescription.
🇹🇭 Overview: From Decriminalization to Reversal
In June 2022, Thailand became the first country in Asia to decriminalize cannabis and remove it from the narcotics list, opening the door to legal cultivation, consumption, and retail (with some caveats). Overnight, hundreds of dispensaries appeared in cities like Bangkok, Chiang Mai, and Phuket. Tourists and locals could legally buy cannabis flowers and infused products, as long as they stayed within certain limits.
However, that liberal regime lacked a robust regulatory framework, leading to a surge in unlicensed dispensaries, weak oversight, and growing concerns about underage consumption and public use. The cannabis scene became a little too relaxed — and the government decided it was time to bring structure back.
On 25 June 2025, the Ministry of Public Health published a ministerial notification in the Royal Gazette, revising the previous “controlled herbs” announcement and imposing stricter controls. Cannabis remains legal, but only for medical purposes. This marks a shift from a gray recreational zone to a clearly defined medical system.
So, to put it simply: Yes, cannabis remains legal in Thailand in 2025 — but only under medical frameworks. Recreational cannabis, as previously tolerated, is now significantly restricted or banned.
⚖️ Key Changes in the 2025 Amendment (What You Must Know)
GACP Certification & Traceability for Growers
Commercial cannabis growers must now obtain GACP (Good Agriculture and Collection Practices) certification from the Department of Thai Traditional and Alternative Medicine (DTAM). Dispensaries must also ensure the cannabis they sell comes from certified sources and must keep traceability records for every batch. This guarantees quality, safety, and transparency throughout the supply chain.
Prescription Requirement & 30-Day Limit
Any purchase or possession of cannabis flower now requires a medical prescription from a licensed professional — such as a doctor, dentist, or Thai traditional medicine practitioner. Each prescription generally allows only up to a 30-day supply, usually around 30 grams. This system helps ensure patients use cannabis responsibly and for genuine medical reasons.
No Unsupervised Smoking in Dispensaries
Dispensaries can no longer allow casual, on-site smoking sessions. Cannabis consumption is permitted only under medical supervision or within private, designated areas. This rule is intended to protect tourists and locals from inadvertently breaking nuisance or public health laws.
Ban on Recreational Sales & Public Use
Cannabis flowers are now officially classified as controlled herbs, which means selling or giving them to non-patients is illegal. Recreational consumption — the kind once found in cafés and bars — is no longer permitted. Violators face up to 1 year in prison and/or a 20,000 baht fine.
🌿 Is Cannabis Legal for Tourists in Thailand in 2025?
Yes, but with clear conditions. Tourists can legally access cannabis in Thailand only with a valid prescription from a Thai-licensed medical practitioner. Foreign medical certificates aren’t valid for cannabis purchase or use within Thailand.
Here’s what visitors need to know:
- You must have a local Thai prescription to purchase or possess cannabis legally.
- The dispensary must verify your prescription before making a sale.
- You can buy up to a 30-day supply, depending on your doctor’s approval.
- Always keep your prescription and receipts on hand — authorities may request proof.
For most travelers, the easiest way to do this is through ThaiCannaMed, which connects you with licensed Thai doctors online to obtain an approved medical cannabis prescription. It’s a quick, legal, and hassle-free process.
🧾 Practical Advice: What Locals & Tourists Should Do
✅ Before You Travel or Purchase
- Schedule an online consultation with ThaiCannaMed to see if you qualify for a prescription.
- Confirm that the dispensaries you plan to visit are properly licensed under the 2025 rules.

🚫 Avoid Unlicensed or Street Sales
Street vendors and unregistered shops are now illegal. Buying from them could lead to fines or even criminal charges. Always check for the DTAM license displayed at the shop.
🚬 Where You Can Consume
Smoking cannabis in public places — including beaches, parks, and streets — is strictly prohibited. It’s considered a public nuisance under Thai law. Use it privately, at home, or in medical-approved facilities.

Keep your ThaiCannaMed prescription, purchase receipts, and original packaging at all times. This simple step can save you trouble if questioned by local authorities.
⚖️ Stay Within the Law
Thailand’s cannabis system is evolving, and enforcement can vary between provinces. Stay updated, follow the regulations carefully, and respect local customs.
