Cannabis Regulation 2025: Balancing Business Opportunities and Legal Boundaries
Background
Cannabis was historically subject to strict prohibition in Thailand, encompassing cultivation, possession, sale, and consumption. In 2022, the government implemented a significant policy shift by removing cannabis from the narcotics list and reclassifying it as a “controlled herb” under a Ministry of Public Health notification issued in the same year. A subsequent notification was published in November 2022 to clarify that cannabis use was intended strictly for medicinal and herbal purposes.
Following a comprehensive policy review in 2025, the Ministry of Public Health issued the Notification Re: Controlled Herbs (Cannabis), B.E. 2568 (2025) (“New Notification”), which took effect on June 26, 2025. This New Notification supersedes the previous notification and establishes a more comprehensive and stringent framework for cannabis control.
Key Provisions of the New Notification
1. Expanded Scope of Control
The New Notification broadens regulatory control from specifically Cannabis Sativa L. to encompass all species within the Cannabis genus of the Cannabaceae family, thereby closing previous legal gaps. Only cannabis flowers are classified as controlled herbs, while other plant parts (leaves, stems, roots) remain exempt unless processed into products containing psychoactive substances.
2. Sales Restricted to Licensed Operators
Licensees under Section 46 may trade or process cannabis exclusively with other licensed parties. Sales to the general public, through online platforms, vending machines, or any form of advertising are strictly prohibited.
3. Quality Control of Cultivation Sources
All cannabis designated for commercial sale or export must originate from cultivation sites certified under Good Agricultural and Collection Practices (GACP) by the Department of Thai Traditional and Alternative Medicine.

4. Medical Use Exemption
Cannabis may be dispensed to individuals possessing a valid prescription from a licensed medical professional. Prescriptions must specify the required quantity and are limited to a maximum 30-day supply, following the format prescribed by the Director-General.
5. Additional Prohibitions
Cannabis sales are prohibited in religious venues, dormitories, public parks, amusement parks, and zoos. Advertising of cannabis or related products remains strictly banned across all channels.
Impact on Stakeholders
The New Notification reinstates a strict control framework governing cannabis use and commerce in Thailand. The regulation presents both opportunities and challenges for various stakeholders.
Positive Impacts
The framework elevates industry standards by ensuring safety and product quality, promotes regulated medical and herbal use, and enables compliant businesses to operate legally and sustainably. It also mitigates health risks for consumers and enhances Thailand’s international reputation as a country that manages cannabis responsibly, particularly in relation to nations where cannabis remains a controlled narcotic.
Challenges
The New Notification presents significant challenges, particularly for small businesses operating outside the licensing system, which may be required to cease operations or substantially modify their business models. The regulation also restricts marketing opportunities and direct-to-consumer sales channels, potentially limiting access for non-patient users or individuals seeking cannabis for general wellness purposes.
Conclusion
Despite the implementation of stricter restrictions, this notification represents a foundational step in establishing a long-term, structured cannabis policy framework for Thailand. Business operators are advised to prepare accordingly, ensure compliance with licensing requirements, and closely monitor regulatory developments to operate sustainably in this evolving landscape.
The regulatory framework reflects Thailand’s commitment to balancing economic opportunities with public health considerations, positioning the country as a responsible leader in cannabis regulation within the Southeast Asian region.
