Marijuana, Hemp, and Kratom in Thailand: The Current Legal Paradigm and Its Complexity

The enactment of Thailand’s Narcotics Code, effective December 10, 2021, marked a key milestone in promoting the commercial applications of cannabis (both marijuana and hemp) and kratom as economic plants—with subsequent regulatory developments continuing this push.

For many decades, cannabis and kratom were classified as category 5 narcotics under the Narcotics Act. However, a movement for the legalization of cannabis and kratom developed over time. First, the legalization of marijuana (Cannabis indica) for medical purposes became effective on February 19, 2019, as prescribed in Amendment No. 7 of the Narcotics Act. Kratom has also been effectively decriminalized (covering consumption, production, disposal, and possession for any purpose) since August 24, 2021, as prescribed in Amendment No. 8 of the Narcotics Act.

The laws governing narcotic and psychotropic substances in Thailand have now taken a significant step forward with the passage of the Narcotics Code, which is intended to be a comprehensive law covering all narcotics and psychotropic substances in Thailand. Most recently, the Ministry of Public Health announced in the Government Gazette on February 2, 2022, that only cannabis extract (both marijuana and hemp) with THC of more than 0.2% by weight will be classified as a category 5 narcotic. This means that seeds, cannabis plants, and inflorescences, if harvested in Thailand, have been removed from the list of category 5 narcotics.

Although the changes to Thailand’s narcotics regulations for cannabis and kratom are intricate, both cannabis and kratom have become a topical issue for farmers and related industries. The plants are new cash crops and have attracted widespread public interest. Currently, we can see fresh kratom leaves and fresh cannabis leaves sold in the market. Unlike products with cannabis derivatives, kratom-based products are not yet available in the Thai market. Although there is an opportunity for developing kratom-based products as energy drinks, infused water, cosmetics, and herbal products, kratom-based products are still in their infancy. For instance, the Thai Food and Drug Administration (FDA) is likely to view that there is no prior art on the use of kratom as a food ingredient. Thus, applications for kratom in energy drinks or infused water must undergo further “novel food safety evaluations.”

On the other hand, cannabis-based products, ranging from pharmaceuticals, foods, and cosmetics to herbal products, have already been launched in the Thai market. Cannabis-based products must be registered with the Thai FDA and their labels/advertisements must comply with all required FDA regulations. Cannabis also has a history of consumption as a food ingredient in Thailand, and therefore, applications for cannabis in the food industry have been able to bypass the food safety evaluation requirements. However, the cannabis industry has faced difficulties in that cultivation of cannabis must receive prior approval by the Thai FDA, while kratom cultivation has no such requirement.

Although kratom and cannabis plants (but not cannabis extract with THC content of more than 0.2% by weight) have been removed from the list of dangerous narcotics, launching finished products containing derivatives of these plants into the market has faced obstacles. These barriers are largely surmountable now, but entrepreneurs, farmers and finished product manufacturers must carefully review the latest developments in the laws and regulations on kratom and cannabis to ensure that they introduce products legally and safely for consumers.

Patent enablement requirements are provided under Article 102 of Vietnam’s Law on Intellectual Property (IP Law). In particular, a patent specification must “fully and clearly disclose the nature of the invention to such an extent that, based on the specification, a person having ordinary skill in the relevant art can implement the invention.” In pharmaceutical and biotechnology patents, this requirement is more complicated and subject to more rigorous assessment. The Patent Examination Guidelines (Guidelines) of the Intellectual Property Office of Vietnam (IP Office) were amended in March 2026 to introduce Annexes III and IV for the pharmaceutical and biotechnology sectors, in which Annex III provides detailed guidelines on the assessment of specification requirements. These amendments were made under a project for strengthening capacity in industrial property examination between the Japan International Cooperation Agency (JICA) and the IP Office. Annex III provides detailed instructions on how examiners assess enablement in a pharmaceutical or biotechnology application, and offers examples of acceptable and unacceptable descriptions with regard to the enablement aspect. Enablement Requirements in Pharma and Biotech Patents Article 12.7 of Circular 10/2026/TT-BKHCN (Circular 10) adds to the requirements of Article 102 of the IP Law that the description must demonstrate the novelty, inventive step, and industrial applicability of the technical solution. For pharmaceutical composition subject matters, Article 12.9 of Circular 10 sets out that the description must present the results of clinical trials and/or the pharmacological effects of the claimed pharmaceutical composition, and must include at least the following information: Substance/mixture used. Testing method (system) employed. Information on the test results. Correlation between the pharmacological effects obtained from the tests and the application of the pharmaceutical product in the prevention, diagnosis, and treatment of diseases. The Guidelines note that pharmacological study results should be presented in a quantified manner, and pharmacological

For the first time, Thailand’s Food and Drug Administration (FDA) has published a consolidated list identifying all substances that have successfully passed its novel food safety evaluation process. The list is a step forward in regulatory transparency, but it also highlights a feature of the Thai regime that food companies often overlook: each approval is tied exclusively to the company that applied for it. A substance’s appearance on the list does not give other companies the green light to use it. This article examines the structure of Thailand’s novel food approval framework, the implications of applicant exclusivity, and the strategic choices it requires of food companies looking to bring novel ingredients to the Thai market. Thai FDA Food Safety Evaluation Framework Notification No. 376 of the Ministry of Public Health requires novel food substances to undergo a food safety assessment, with an exemption only for novel foods manufactured exclusively for export. The framework also encompasses “foods that do not qualify as novel foods” but which present characteristics warranting a safety evaluation, such as differing quality standards, increased serving sizes, or applications in specific food categories, where such changes affect consumption levels, nutritional value, or consumer safety. The recently published list of foods that passed the safety evaluation by the Thai FDA is structured by substance category and identifies the approved company (domestic manufacturer or importer), country of origin, substance name and trade name, approved purpose of use, and date of the Thai FDA’s approval notification certificate. A notable feature of Thailand’s novel food regime is that the approval result is tied exclusively to the company that submitted the application. Publication of the consolidated list does not constitute a general authorization to use the approved substances. The Thai FDA’s approval certificate specifies the approved conditions of use and the requirements
