Cannabis Business Compliance in Thailand 2026: What You Need to Know

Current Legal Status: Decriminalized but Regulated

Cannabis in Thailand occupies a unique legal position as of 2026. Following the landmark delisting of cannabis from the narcotics schedule in June 2022, Thailand became the first Asian country to decriminalize cannabis. However, the regulatory framework has been evolving significantly since then. The Cannabis and Hemp Act, which has been through multiple drafts and parliamentary debates, establishes the framework for legal cannabis use and commerce. Key points of the current status: (1) Cannabis is not a narcotic under the Narcotics Act, (2) Recreational use in public spaces remains restricted — public consumption can result in fines, (3) Cannabis products with THC content above 0.2% in extracts are controlled, (4) Commercial cannabis operations require FDA licenses, (5) Personal cultivation is permitted with registration through the FDA's Plook Ganja app.

FDA License Types

The Food and Drug Administration (FDA) oversees cannabis licensing under delegated authority. Several license types exist depending on the intended activity:

Cultivation License

Required for growing cannabis beyond personal use (more than 15 plants or for commercial purposes). Applicants must: register the cultivation site with the FDA, demonstrate compliance with good agricultural practices (GAP), maintain records of all plants (seed-to-sale tracking), and submit to periodic inspections. License fee: THB 5,000-50,000 depending on scale.

Processing and Manufacturing License

Required for extracting, processing, or manufacturing cannabis products. This includes: CBD/THC extraction, edible production, cosmetic manufacturing, and medical product formulation. Requirements include: GMP-certified facility, qualified pharmacist or chemist on staff, product testing capabilities or contracts with certified laboratories, and detailed standard operating procedures (SOPs).

Retail and Distribution License

Required for selling cannabis products to consumers. Retailers must: verify that all products sold have proper FDA registration, maintain purchase and sales records, ensure products are properly labeled (ingredients, THC/CBD content, health warnings), and not sell to persons under 20 years of age. Online sales face additional restrictions and platform-specific rules.

THC Limits

The regulatory framework establishes clear THC thresholds: (1) Hemp products: less than 0.2% THC by dry weight — these face lighter regulation and can be used in food, cosmetics, and wellness products. (2) Cannabis extracts: products with THC above 0.2% are subject to stricter controls and are primarily regulated as traditional medicine or controlled products. (3) Flower and buds: unprocessed cannabis flower is legal for sale by licensed retailers but subject to age restrictions and labeling requirements. (4) Food and beverages: cannabis-infused food and drinks must not exceed 0.2% THC and must be clearly labeled. All THC/CBD content claims must be verified by laboratory testing from a certified lab.

Advertising Ban

Advertising of cannabis products is heavily restricted. Under the Cannabis and Hemp Act and FDA regulations: (1) No advertising that promotes recreational cannabis use, (2) No health claims unless the product is registered as a traditional medicine or health supplement with approved claims, (3) No advertising targeting minors, (4) No use of cannabis imagery in promotional materials for non-cannabis businesses, (5) Social media promotion is subject to the same restrictions. Violations carry fines of up to THB 300,000 and potential imprisonment. The FDA's Digital Surveillance Division actively monitors online cannabis advertising.

Import and Export Restrictions

Despite domestic decriminalization, cannabis remains a controlled substance under international treaties (the 1961 UN Single Convention on Narcotic Drugs). Consequently: (1) Import of cannabis products requires specific FDA approval and is limited to approved medical, research, or industrial purposes, (2) Export is similarly restricted and requires both Thai export permits and import permits from the destination country, (3) Travelers cannot bring cannabis into or out of Thailand in personal luggage — this remains a criminal offense in most destination countries, (4) Hemp-derived products (under 0.2% THC) have somewhat relaxed import rules but still require FDA registration.

Foreign Ownership Restrictions

The Foreign Business Act B.E. 2542 (1999) applies to cannabis businesses just as it does to other commercial activities. Critically: (1) Foreigners cannot directly own a cannabis cultivation, processing, or retail business — these fall under FBA-restricted categories, (2) The standard 51/49 Thai company structure is required, with genuine Thai majority shareholders, (3) BOI promotion is not currently available for cannabis retail or cultivation businesses, though certain cannabis-related research or biotechnology activities may qualify under specific BOI categories, (4) Foreign investment through joint ventures with Thai partners is the most common structure. The DBD scrutinizes cannabis company registrations closely for nominee shareholder arrangements.

Compliance Inspections

Licensed cannabis businesses are subject to regular inspections by: (1) FDA inspectors — checking license compliance, product quality, labeling, record-keeping, and THC limits. Inspections may be scheduled or unannounced. (2) Local health authorities — verifying premises hygiene and safety standards. (3) Excise Department — if applicable, checking tax compliance on cannabis products. (4) Police — enforcement of age restrictions, operating hours, and advertising rules. Businesses must maintain comprehensive records available for inspection: cultivation logs, processing records, laboratory test results, sales records, and waste disposal documentation. Records must be retained for at least 5 years.

Penalties for Non-Compliance

Penalties vary by offense: (1) Operating without a license: fine up to THB 300,000 and/or imprisonment up to 3 years, (2) Selling to minors (under 20): fine up to THB 300,000 and/or imprisonment up to 3 years, (3) Advertising violations: fine up to THB 300,000, (4) Product safety violations (exceeding THC limits, contamination): fine up to THB 200,000 and product recall, (5) Import/export without authorization: penalties under both the Cannabis and Hemp Act and Customs Act B.E. 2560 (2017), (6) Repeated violations: license revocation and permanent ban from the industry.

Practical Advice

The cannabis regulatory landscape in Thailand continues to evolve. Before investing: (1) Engage a Thai lawyer experienced in FDA licensing and cannabis regulation. (2) Monitor legislative developments — new regulations are issued frequently. (3) Budget generously for compliance costs (laboratory testing, record-keeping systems, security). (4) Do not rely on the 2022 "free for all" mentality — enforcement has tightened significantly since 2023. (5) Consider starting with hemp-derived products (under 0.2% THC) which face lighter regulatory requirements. (6) Join industry associations for regulatory updates and advocacy.
