Cannabis Laws in Thailand: What Visitors Need to Know

Thailand’s cannabis legal landscape has seen major shifts over the past few years.

In June 2022, the government removed cannabis flower from the country’s list of narcotics and decriminalised its use and possession, making Thailand the first country in Asia to do so. That reform was enacted under a policy that encouraged both medical and broader access to the plant, and tens of thousands of dispensaries and retailers quickly opened across the country.

This early decriminalisation was driven by Health Minister Anutin Charnvirakul and was framed as a move to boost medical access and community‑based agriculture.

However, because those initial changes lacked a comprehensive legal framework, recreational use spread rapidly, including in tourist areas, without clear rules on sales, prescriptions, or public consumption. This lack of regulation generated concern among officials about access by minors and social impacts, and it became a political issue.

New Rules on Cafes, Dispensaries and Consumption

In June 2025 the Thai government introduced a new regulatory regime that tightened control over cannabis. On 26  June  2025, an announcement published in the Royal Gazette reclassified cannabis flower as a “controlled herb” under the Protection and Promotion of Thai Traditional Medicine Knowledge Act B.E. 2542, rather than leaving it uncontrolled despite decriminalisation.

Under this law, the sale, possession and consumption of cannabis flower is restricted to those with a valid medical prescription from a licensed physician, dentist, or traditional medical practitioner, and such prescriptions are typically limited to a 30‑day supply. Recreational use is now explicitly prohibited, and public consumption can be penalised as a public nuisance.

The 2025 rules also imposed strict requirements on cannabis businesses: dispensaries must hold proper licences, source cannabis only from certified farms, track inventory, and ensure medical oversight of sales. Many shops either closed or failed to renew licences due to these requirements, with thousands shutting down by early 2026.

So although Thailand’s 2022 decriminalisation created a period of widespread recreational cannabis use, the current legal framework (since mid‑2025) prioritises medical access with specific prescriptions and regulatory controls, and prohibits recreational use and unlicensed sales. Recreational cannabis is no longer freely sold or consumed under the law, and penalties exist for violations of the medical‑only regime.

Is Marijuana Legal in Thailand?

Cannabis is legal only for medical purposes. To legally possess, buy, or use cannabis, you must have a prescription from a licensed Thai doctor, and products must come from authorised dispensaries. Possession or use of high-THC cannabis without a prescription can result in fines or imprisonment. Exporting cannabis or taking it out of Thailand remains illegal.

Can I grow cannabis at home or commercially?

Home cultivation for medical use requires registration with the Thai authorities. Commercial growers must have a licence from the Food and Drug Authority (FDA). Unauthorized cultivation can lead to legal penalties.

Are cannabis cafés still open in Thailand?

No. Recreational cafés and consumption spaces that briefly operated in the past have mostly closed or been reclassified under stricter medical regulations. There are currently no legal venues for recreational use, so visitors should not attempt to consume cannabis outside a medical context.

Can I smoke cannabis in Thailand?

No. Smoking or using cannabis in public, including streets, hotels, bars, or other venues, is illegal and can lead to fines, confiscation, or arrest. Even medical users should consume cannabis only at home or in licensed medical facilities.

What are the penalties for cannabis possession in Thailand?

• Possession without a prescription: fines and/or imprisonment.
• Production, import, or export without a license: up to 15 years imprisonment and heavy fines.
• Public consumption or unlicensed sale: fines and/or prison, depending on severity.

Can foreigners access medical cannabis in Thailand?

Yes, but only with a prescription from a licensed Thai doctor. Products are generally lower in THC than recreational cannabis elsewhere. Stronger products remain tightly controlled.

Is there a cannabis “tourist zone” or sandbox?

No. Proposals for cannabis tourism zones have not been implemented. Tourists cannot legally consume or purchase cannabis unless they hold a valid Thai medical prescription.

Tips for visitors:

• Only use cannabis with a legitimate Thai medical prescription.
• Buy products from licensed dispensaries.
• Never attempt to take cannabis out of Thailand.
• Avoid public use—consumption should be private and at home.
