Thailand made history in June 2022 as the first Asian country to decriminalize cannabis. Since then, a thriving cultivation industry has emerged — and then transformed. Following the June 2025 reclassification of cannabis flower as a “controlled herb,” the farming landscape has shifted from a recreational free-for-all to a regulated, medical-focused agricultural sector.
Whether you are a Thai farmer considering cannabis as a crop, a community enterprise planning a cultivation project, or an international investor exploring opportunities, this guide covers everything you need to know about legally growing cannabis in Thailand in 2026.
Current Legal Framework for Cannabis Cultivation
The June 2025 Reversal
On June 25, 2025, Public Health Minister Somsak Thepsuthin signed a proclamation reclassifying cannabis flower buds (ช่อดอก) as a “controlled herb” under the Protection and Promotion of Thai Traditional Medicine Knowledge Act B.E. 2542 (1999). This effectively ended the open recreational market and repositioned cannabis cultivation as a medical and traditional medicine activity. For full details on the current legal framework, see our Thailand Cannabis Laws 2026 guide.
Key point: Cannabis flower is not reclassified as a narcotic under the Narcotics Act. This is a legally significant distinction — cannabis farming remains legal, but under a stricter regulatory framework focused on medical applications.
The Cannabis and Hemp Act — Still Pending
The Cabinet approved a draft Cannabis and Hemp Act (ร่าง พ.ร.บ.กัญชา กัญชง) on June 24, 2025. As of March 2026, this act has not yet passed parliament and remains under committee review. Current regulations operate under a combination of ministerial orders, FDA rules, and existing pharmaceutical laws rather than a single dedicated cannabis statute.
This means the regulatory landscape could change when the act passes. Farmers and investors should monitor legislative developments closely.
What This Means for Farmers
- Cannabis cultivation is legal with proper licensing and registration
- All cannabis flower produced must be directed toward medical and traditional medicine channels
- Community enterprises remain the primary pathway for cultivation
- Security, tracking, and quality standards are mandatory
- The market has contracted but stabilized around medical demand
Who Can Grow Cannabis in Thailand
Thai Nationals and Households
Thai citizens can cultivate cannabis at home after registering through the “Pluk Kan” (ปลูกกัญ) app or the Thai FDA website. However, household cultivation is subject to plant limits and purpose restrictions. Home-grown cannabis flower cannot be sold commercially without proper licensing.
Community Enterprises (วิสาหกิจชุมชน)
Community enterprises are the most common and accessible pathway for cannabis farming in Thailand. This model was designed to ensure that economic benefits flow to local Thai communities rather than large corporations.
Requirements to form a cannabis community enterprise:
- Minimum 7 members from the same district, each from a different household registration
- Register with the district agriculture office — site inspection occurs within 7-15 days
- Partner with a government agency — typically a provincial health promotion hospital, university, or government department
- Sign a Memorandum of Agreement (MOA) — not merely an MOU; this is a binding partnership
- Complete at least 2 training sessions on cannabis cultivation and regulations
- Register cultivation with the FDA via the Pluk Kan system
Important restriction: Under the community enterprise model, all flower buds must be sent to the Department of Thai Traditional Medicine for pharmaceutical extraction. Community enterprises may commercially use stems, roots, branches, and leaves, but cannot sell flower buds directly.
Commercial Companies
Private companies can obtain cultivation permits under Section 46 of the relevant pharmaceutical regulations. This covers research, processing, export preparation, and distribution. Requirements include:
- Thai-registered company structure
- GACP (Good Agricultural and Collection Practices) certification
- Full compliance with DTAM standards
- Detailed cultivation, processing, and distribution plans
Foreign Nationals
Foreigners cannot directly hold cannabis cultivation licenses in Thailand. The regulatory framework strongly favors Thai nationals and Thai-registered entities. However, foreign participation is possible through:
- Thai-majority joint ventures where Thai partners hold the cultivation license
- BOI (Board of Investment) registered companies for agricultural technology and processing — see our cannabis business guide for more on licensing options
- Advisory and technology partnerships with licensed Thai operators
- Investment in processing and value-added operations rather than direct cultivation
During the initial 5-year period following decriminalization (2022-2027), cultivation is restricted to partnerships involving government agencies or community enterprises working with the government.
Licensing and Registration Process
Step 1: FDA Registration
All cannabis cultivators must register with the Thai Food and Drug Administration (FDA). Registration is done through the Pluk Kan (ปลูกกัญ) system — either the mobile app or the web portal at cannabisinfo.fda.moph.go.th.
Registration requires:
- Thai national ID or company registration documents
- GPS coordinates of the cultivation site
- Cultivation plan detailing strains, quantities, and intended use
- Security plan for the facility
Step 2: GACP Certification
The Department of Thai Traditional and Alternative Medicine (DTAM) requires Good Agricultural and Collection Practices (GACP) certification under Thai or EU standards.
GACP certification covers:
- Environmental monitoring — soil, water, and air quality records
- Cultivation inputs — fertilizers, pesticides (organic preferred), growing media
- Employee hygiene — training, protective equipment, sanitation protocols
- Harvest procedures — timing, handling, drying, and curing standards
- Batch tracking — complete seed-to-sale traceability
- Quality testing — cannabinoid profiles, contaminant screening
Certification must be renewed every 3 years.
Step 3: Security Compliance
Cannabis farms must implement physical security measures:
- Concrete perimeter fencing with barbed wire or equivalent barriers
- CCTV camera system covering all cultivation and storage areas
- Security personnel during operating hours
- Access control — visitor logs, restricted entry zones
- Inventory tracking — daily plant counts, weight records
Step 4: Ongoing Compliance
Licensed cultivators must maintain:
- Monthly transaction records using official forms (Phor.Tor.27, 28, 29)
- Harvest and distribution logs submitted to DTAM
- Quality testing results for each batch
- Annual license renewal documentation
Cannabis vs Hemp: Understanding the Distinction
Thailand maintains a clear legal distinction between cannabis (กัญชา) and hemp (กัญชง), and this distinction significantly affects what you can grow and sell.
| Factor | Cannabis (กัญชา) | Hemp (กัญชง) |
|---|---|---|
| THC Content | Above 0.2% in extracts | Not exceeding 1.0% by dry weight |
| Legal Status | Controlled herb (flower buds) | Permitted for industrial and commercial use |
| Regulation | Under traditional medicine framework | Lighter regulatory pathway |
| Market Access | Medical dispensaries only | Food, textiles, cosmetics, construction |
| Flower Sales | Requires PT 33 prescription | Less restricted |
| Export | Prohibited | Limited pathways for CBD products |
Why Hemp May Be the Better Opportunity
For many farmers, hemp cultivation offers a more straightforward business model:
- Broader market access — hemp products can be sold as food ingredients, textiles, construction materials, cosmetics, and wellness products without medical restrictions
- Lower regulatory burden — fewer security requirements and simpler licensing
- Industrial applications — hemp blocks (40% lighter than regular building blocks), hemp boards (20% lighter than MDF), bioplastics, and fiber products
- CBD extraction — hemp-derived CBD products (under 0.2% THC) are a growing market
- Food products — hemp seeds, hemp seed oil, and hemp protein are increasingly popular in Thai and export markets

Total Timeline: 12-18 Months from Decision to First Harvest
Thai Cannabis Strains and Genetics
Thailand has a rich cannabis genetic heritage. Thai landrace sativas are legendary in the global cannabis world and offer unique advantages for local cultivation.
Thai Landrace Varieties
- Thai Stick — the original Thai sativa that became famous worldwide in the 1970s. Long flowering time (14-20 weeks) but produces distinctive, aromatic flower
- Thai Sativa — various regional landrace genetics adapted to Thailand’s tropical climate over centuries. Naturally resistant to local pests and mold
- Highland Thai — genetics from northern mountain regions, slightly shorter flowering times
Modern Genetics in Thailand
Many Thai farms also grow modern hybrid strains that offer:
- Shorter flowering times (8-10 weeks vs 14-20 for pure Thai sativas)
- Higher yields per plant
- More consistent cannabinoid profiles
- Better suitability for indoor cultivation
Seed Sourcing
Seeds and clones should be sourced from:
- Registered Thai seed banks and nurseries
- Government research institutions
- Established cannabis farms with breeding programs
- Licensed importers (with proper documentation)
Organic Cannabis Farming in Thailand
Thailand’s tropical climate and agricultural traditions make it well-suited for organic cannabis cultivation. Organic practices are increasingly valued in the medical cannabis market.
Soil Preparation
Thailand’s diverse soil types affect cannabis cultivation differently:
- Laterite soils (common in the northeast) — need organic matter amendments
- Alluvial soils (river basins, central plains) — naturally fertile, excellent for cannabis
- Sandy loam (coastal areas) — good drainage, may need nutrient supplementation
- Mountain soils (north) — often rich in organic matter, ideal for outdoor growing
Organic Pest Control
Thailand’s tropical environment means year-round pest pressure. Effective organic solutions include:
- Neem oil — broad-spectrum organic pesticide effective against most cannabis pests
- Beauveria bassiana — beneficial fungus that controls whiteflies, thrips, and aphids
- Bacillus thuringiensis (Bt) — biological control for caterpillars and larvae
- Predatory insects — ladybugs, lacewings, and predatory mites
- Companion planting — basil, marigolds, and lemongrass as natural pest deterrents
GAP and Organic Certification
While not mandatory, Good Agricultural Practices (GAP) certification is strongly encouraged and can command premium prices. Organic certification through Thai standards or international bodies (USDA Organic, EU Organic) adds further market value, particularly for export-oriented CBD and hemp products.
Export Regulations
Cannabis Flower
Export of cannabis flower from Thailand is strictly prohibited. Violations carry severe penalties including up to 1 year imprisonment and 20,000 THB fines.
CBD and Hemp Products
Hemp-derived products with less than 0.2% THC have limited export pathways:
- Requires FDA export approval
- Destination country compliance verification
- Pharmaceutical-grade documentation
- Batch testing and certificates of analysis
Thailand is actively developing its position as a CBD exporter. The National Nanotechnology Center (NANOTEC) has developed nanoparticle CBD delivery technology to enhance the value and effectiveness of export products. However, the export infrastructure remains in development.
Import
Cannabis import into Thailand is strictly prohibited under all circumstances.
Market Outlook: Cannabis Farming in 2026 and Beyond
