Thailand Cannabis FAQ


Is marijuana legal in Thailand?

The short answer is that Thailand legalized the medicinal use of cannabis, including marijuana, in 2019. The longer is that it is complicated.

Unlike many other countries that legalized medical cannabis, Thailand still keeps tight control over the growth, processing, prescription, and distribution of cannabis.

Marijuana and THC are still considered to be Category 5 Narcotics in Thailand with possession carrying penalties of anywhere from 5 – 15 years.

What is the penalty for marijuana possession in Thailand?

Despite legalizing cannabis for medical purposes in 2019, Thailand still has some of the strictest drug laws in the world.

Marijuana is still considered a Category 5 controlled substance which carries a penalty of up to 5 years imprisonment for mere possession. The possession of over 10kg (22 pounds) can result in a prison term of up to 15 years.

How do I get a medical marijuana prescription in Thailand?

You must go to a licensed clinic where a health provider, usually a doctor unless you see a Thai traditional medicine provider, who has received specialized training in cannabis treatment, will evaluate your medical condition to determine if cannabis is appropriate for your condition.

If the health professional determines that cannabis is an appropriate, they will provide you with a certificate that states that you are under the care of that physician and that they are prescribing cannabis.

Clinics are also dispensaries, so you will purchase your cannabis medication right there at the clinic. Some clinics offer refills via online services such as LINE.

Typically, certificates are good for only 30-days. To continue treatment, you must revisit the clinic.

Please note that currently the demand for cannabis medicines is much greater than the supply of cannabis available to produce the medicine. Many clinics, especially government-run clinics, will not see foreign patients for cannabis-related treatment (foreigners can receive other types of medical treatment at government-run clinics and hospitals).

What type of medical marijuana is available in Thailand?

At the moment, the two primary forms of medicinal cannabis are THC and CBD tinctures. The CBD is typically a 1:1 ratio CBD to THC formulation and the THC is just THC.

Flower is not available at this time.

Can I use my medical marijuana prescription from home while in Thailand?

At the moment, no. However, there is a bill before Thailand’s parliament which would allow foreigners to import and export CBD for personal medical use, if the foreigner has an appropriate prescription from either a Thai or foreign physician.

Can foreigners get medical marijuana in Thailand?

There are no laws in Thailand that distinguish between Thai and foreigner patients for medical marijuana.

That said, most government clinics where cannabis is available have waiting lines so long that they will not accept foreigners as patients.

Are there marijuana dispensaries in Thailand?

As the law currently stands, Thailand has opted to forego traditional marijuana dispensaries.

Cannabis therapy is prescribed by a medical professional who has received specialized cannabis-medicine related training who can only prescribe cannabis at a clinic that has also applied to prescribe and distribute medical cannabis.

In other words, there is no separation between getting a medical marijuana card and a dispensary that sells the cannabis medicine. They are typically the same entity and are simply referred to as clinics.

Why is marijuana illegal in Thailand?

Believe it or not, despite having some of the harshest drug laws in the world, marijuana has been an integral part of Thai traditional medicine for hundreds of years.

Prior to the Marijuana Act B.E. 2477 (1934) there were no laws prohibiting the cultivation or use of marijuana. Even with the Marijuana Act B.E. 2477, marijuana was still widely used in Thailand and enforcement was lax.

However, under mounting pressure from the US and other countries, the Thai government passed the Thailand Narcotics Act, B.E. 2522 (1979) which introduced much harsher penalties and enforcement.

Has Thailand decriminalized marijuana?


Decriminalization typically refers to ceasing to treat something as a crime. For instance, in places where marijuana has been decriminalized, one might receive a citation or ticket rather than being arrested.

Can I grow marijuana in Thailand?

While there are various proposals that have been submitted to the Thai parliament, currently, only entities that have applied for, and have received, permission from the Thai government can grow marijuana.
