Until June 9, 2022, cannabis and hemp had been classified as a category 5 narcotic under Thailand’s 1979 Narcotics Act. For many years, all activities related to the plants and their derivatives was heavily restricted until regulatory liberalization began in February 2019 with an amendment to the Narcotics Act. Over the next few years, restrictions on specific types or uses of cannabis and hemp were gradually loosened, and then Thailand became the first country in Asia to permit growing, selling, and using the plant for both medical and other permitted purposes when it delisted both cannabis and hemp plants and their unprocessed parts from the Narcotics Code on June 9, 2022.

This delisting now allows the private sector to grow, possess, sell, and use locally cultivated cannabis and hemp plants without a license. However, the Narcotics Code still regulates cannabis and hemp extracts containing tetrahydrocannabinol (THC) of more than 0.2%. Making or handling a substance with THC over this limit still requires a license, with limited exceptions.

However, the breadth of this liberalization will likely be tempered in the future. The draft Cannabis and Hemp Act, an omnibus law currently under the Thai Parliament’s consideration, is expected in the months to come. This act will specifically govern cannabis and hemp, including by imposing controls such as new restrictions or an enhanced licensing regime.

Most of the product classifications discussed here are based upon THC content, and on the presence of cannabidiol (CBD) in the products. As THC is considered a psychoactive substance—in comparison to CBD, which is not psychotropic and has been applied in various therapeutic indications—a higher THC content may therefore be associated with a greater risk of abuse, and thus stricter regulations will likely apply in Thailand. Under the most recent legal amendments, Thai law defines cannabis as in the Cannabis sativa L. subsp. indica, and hemp as Cannabis sativa L. subsp. sativa with no more than 1.0 % THC by dry weight in its leaves and inflorescence.

The key regulatory body for cannabis and hemp-related products is the Thai Food and Drug Administration (Thai FDA), a government agency operating under supervision of the Ministry of Public Health. Working closely with the Narcotics Control Committee, the Thai FDA is mainly responsible for granting and administering licenses and post-marketing control, among others. Representatives of the Thai FDA also sit on most of the national policymaking committees. One of the other Thai government bodies involved in the regulation and control of cannabis and hemp is the Department of Agriculture (under the Ministry of Agriculture and Cooperatives), which administers the rules on the importation of plant seeds (e.g., cannabis and hemp seeds).


Product Classification

Activity-Focused Regulatory Overviews

Cultivating Cannabis/Hemp

Following their June 9, 2022, delisting, Thai nationals may freely cultivate cannabis and hemp plants and trade unprocessed plant parts and crude resins in Thailand without a license.

As stated earlier, however, the current breadth of this liberalization is expected to be temporary. Upon promulgation of the current draft Cannabis and Hemp Act, the industry is likely to face new restrictions and an enhanced licensing regime.

Companies and importation activities are subject to various regulations. For companies, agricultural activities (including growing cannabis/hemp) are still reserved for majority Thai-owned companies.

Importation of cannabis/hemp plants and most unprocessed parts is still prohibited, except for cannabis/hemp seeds, which may be imported under the rules and procedures of the Plant Act (1975) and Plant Quarantine Act (1964).

Producing or Importing Cannabis/Hemp Extracts and Seed Oils

Industrial extraction of cannabis or hemp still requires a Thai FDA license under the Narcotics Code.

After the June 9, 2022, delisting, the following products are now deregulated:

  • Extracts containing 0.2% or less THC by weight produced from domestically grown plants and under license from the Thai FDA, and
  • Seed oils produced from domestically grown seeds.

These deregulated products may be sold, possessed and consumed without a license under the Narcotics Code. Howver, handling any extract or oil that does not fall within the conditions set out above requires a license from the Thai FDA under the Narcotics Code.

Importation. Importation of any extract or oil is still prohibited.

Producing or Importing Medical Cannabis/Hemp and Other Herbal Products

Production. Irrespective of THC content, medical cannabis/hemp (including Thai traditional medicines and cannabis oils) and other herbal products (including herbal cosmeceuticals and nutraceuticals) now fall under the purview of the Herbal Product Act (2019). The act, along with its subsequent implementing regulations, provides licensing and product registration requirements for domestic production and distribution of these products.

Importation. Importation of these products is still largely prohibited with a few exceptions: Thai government agencies importing goods for treatment of patients, public academic institutions importing for research purposes, and anyone importing for human clinical trials, subject to the licensing procedures of the Thai FDA under the Herbal Products Act.

Producing or Importing Modern Drugs Formulated with Cannabinoids

Modern drugs formulated with cannabis, hemp extract, or other cannabinoids require regulatory review and licensing from the Thai FDA under the Drug Act. The licensing rules and procedures are already in place through existing ministerial regulations and notifications. Notably, a drug manufacturer or importer license is required for the business operator, and a drug registration certificate is required to market a particular modern drug formulation.

Producing or Importing Cosmetics with Hemp- and Cannabis-based Ingredients

Production. Domestically produced cosmetics may contain any or combination of hemp seed oils, hemp seed extracts, parts of hemp (except inflorescence), parts of cannabis (except inflorescence and seeds), and CBD extracts, provided that the raw materials are obtained from plants grown in Thailand. The production requires a Thai FDA license under the Cosmetics Act. Additionally, the products themselves must comply with the specifications prescribed by the relevant ministerial notifications.

Cannabis seeds, cannabis seed oils, and inflorescences of cannabis and hemp, regardless of their origins, are prohibited from cosmetic product formulations.

Importation. Importation of cosmetic products containing hemp- or cannabis-based ingredients is still prohibited.

Producing or Importing Food, Beverages, Food Supplements, or Food Additives with Hemp- and Cannabis-based Ingredients

Production. Food products may contain hemp seeds, hemp seed oils, hemp seed proteins, parts of hemp (except inflorescence), parts of cannabis (except inflorescence and seeds), and CBD extracts, provided that these are obtained from plants grown in Thailand. For domestically produced goods, a Thai FDA license is required under the Food Act, and the product must comply with the relevant ministerial notifications.

While this allowance is applicable to many food products, there are exceptions. For example, no part of cannabis or hemp may be added to food for infants, food for young children, or energy drinks. In addition, certain foods do not allow addition of cannabis and hemp. Certain other foods allow use with conditions. Because of this variation in rules for different kinds of food, it is important to check the relevant regulations to ensure compliance.

Cannabis seeds, cannabis seed oils, and inflorescences of cannabis and hemp are not allowed as ingredients in any food product.

Importation. Importation of food products containing hemp- or cannabis-based ingredients is still prohibited—even if the cannabis- or hemp-based ingredients came from plants grown in Thailand.

Ready-to-Eat Foods and Beverages

Thai restaurants and cafés are allowed to use cannabis parts (except inflorescence and seeds) and hemp parts (except inflorescence) in their recipes.

Crop and processing infrastructure

The Cannabis and Hemp Act drafting committee is planning to organize cultivation into three classes. Small cultivators, with no more than 10 plants per household, may not have to pay fees but will have to notify the Thai FDA of their growing activities. Medium cultivators, with less than 32,000 square meters (<20 rai) under cultivation, will have to go through additional bureaucratic procedures and pay additional fees. Large cultivators, with over 32,000 square meters (>20 Rai) under cultivation, will be considered commercial cultivators and require FDA approval. Fees for large cultivators are likely to include both monthly and annual payments.

The committee has decided that modern medical practice and traditional physicians, and other healthcare professionals cultivating cannabis for medical purposes, will only be required to notify the FDA of their activities (similar to the requirements for small cultivators).

The Narcotics Division of the Thai FDA published handbooks on growing and handling cannabis crops in 2021. Cultivators can choose among outdoor, semi-outdoor, and indoor cultivation. Outdoor cultivation is described as being low-cost and suitable for Thai cannabis varieties, with the drawbacks of limited pest-control options and harvesting taking place annually. On the other hand, indoor cultivation comes with higher costs but with the advantages of better quality control and year-round harvesting. As for the import of cultivation and processing infrastructure, such as equipment for crop maintenance, testing, extraction, formulation, and packaging, relevant regulations are in place and need to be considered.

Intellectual Property


On January 28, 2019, the Thai government issued an ordinance to reject a number of Thai patent applications filed by foreign applicants, all of which related to medical formulation or use of cannabis-derived active ingredients. The ordinance was issued to annul any private exclusive rights that could block access to medical cannabis following its legalization, and it was terminated on February 19, 2019, when cannabis legalization took effect. Since then, patentability has once again been examined against the previously established rules of the Patents Act. This means that generally, an application related to cannabis is eligible for a patent if it is not for recreational purposes; not a diagnostic or therapeutic method; and not the plant itself, its part, or crude extract.


Generally, trademark protection for goods or services related to legalized use of cannabis or hemp is available in Thailand, as long as the trademark meets the usual requirements for registration.
