Cannabis Business License Thailand 2026: Complete Guide

Starting a cannabis business in Thailand in 2026 requires navigating a regulatory framework that has changed significantly since the June 2025 re-regulation. The open market era is over — all cannabis businesses must now operate within a medical framework with proper licensing, practitioner oversight, and compliance procedures.

This guide covers the licensing requirements, costs, ownership rules, and practical steps for opening a cannabis business in Thailand under the current regulations.

The Current Regulatory Framework

Thailand’s cannabis regulations have tightened significantly across 2025 and 2026. Key changes affecting businesses:

• Cannabis flower is classified as a “controlled herb” under ministerial orders since June 2025
• All dispensaries must operate under medical supervision with a licensed practitioner on-site
• PT 33 prescriptions are required for all cannabis flower sales
• CBD products with less than 0.2% THC remain unregulated and do not require special licensing for retail
• Cultivation requires specific licensing from the FDA Thailand (อย.)
• Extracts above 0.2% THC remain Category 5 narcotics under a new ministerial regulation effective 26 April 2026, limited to four permitted uses (medical, research, industrial, narcotics suppression). Old 2020–2021 extract licences are valid only until 31 December 2026.
• Cannabis-flower sell/process/export licences are subject to four new substantive criteria under Ministerial Regulation (No. 2) B.E. 2569, published in the Royal Gazette on 30 April 2026 — see the dedicated section below.

The Cannabis and Hemp Act, which would provide a comprehensive legal framework, is in formal public consultation through 21 May 2026 before parliamentary submission. Current businesses operate under the layered framework of ministerial regulations described above.

The April 30, 2026 Cannabis-Flower Licensing Overhaul

Ministerial Regulation on the Permission for Study, Research, or Export of Controlled Herbs, or Sale, or Processing of Controlled Herbs for Commercial Purposes (No. 2) B.E. 2569 — published in the Royal Gazette on 30 April 2026 — adds cannabis-flower-specific criteria on top of the existing controlled-herbs licensing framework. All new applications, all pending applications, and all renewals for sell/process/export licences for cannabis flower are processed under these criteria.

Every applicant must satisfy all four of the following, cumulatively. Failure on any one is grounds for refusal.

1. Premises Ownership or Written Consent

The applicant must hold ownership or possessory rights over the licensed premises, or provide written consent from the owner. This is intended to close off undocumented sub-leasing arrangements common during the 2022–2024 boom.

2. Dedicated, Quality-Controlled Storage

Storage space must be appropriately sized for planned volumes and equipped to maintain cannabis-type controlled herbs in good condition. Cannabis flower must be:

• Stored separately, not mixed with other materials
• Not in direct contact with the floor
• Held in conditions that protect quality (temperature, humidity, light protection)

3. Qualifying Applicant Status

The applicant must already hold at least one of the following credentials:

• Hospital operating licence (under the Sanatorium Act)
• Herbal product manufacturing or sales licence (Herbal Products Act B.E. 2562)
• Pharmaceutical/drug manufacturing or sales licence (Drug Act)
• Category 5 narcotics manufacturing licence (specific to cannabis/hemp extracts)
• Folk healer certification (หมอพื้นบ้าน) under the Thai Traditional Medical Practice Act
• Or be a cultivation site supplying licensed Section 46 buyers

The standalone retail-dispensary model from the open-market era no longer qualifies. Operators must anchor to the health sector.

4. DTAM-Trained Staff On Duty

At least one staff member who has completed training from the Department of Thai Traditional and Alternative Medicine must be physically present at the establishment throughout all operating hours. Gaps in coverage are grounds for non-renewal.

Plus: Odor and Smoke Elimination

Establishments handling cannabis flower must be equipped with an effective odor and smoke elimination system. Activated carbon filtration, sealed extraction systems, and documented maintenance are the standard interpretation.

Renewal as Re-Qualification

Existing licences from before 30 April 2026 remain valid until their original expiry date — there is no immediate revocation. However, renewal is treated as a full re-qualification under the four criteria above. Operators previously suspended for non-compliance are permanently barred from renewal.

Ownership Requirements

Thai Ownership Rule

Under the Foreign Business Act, cannabis businesses require a minimum 51% Thai ownership. Foreign nationals can own up to 49% of a cannabis business.

Important:

• The Thai majority partner must be a genuine stakeholder with real investment
• “Nominee” arrangements (using a Thai person’s name without genuine investment) are illegal and can result in criminal prosecution
• Board of Investment (BOI) privileges do not currently extend to cannabis retail businesses
• Some cultivation operations may qualify for agricultural BOI incentives — consult a licensed Thai attorney

Business Structure Options

• Thai Limited Company (บจก.) — Most common structure. Minimum 3 shareholders, at least 51% Thai ownership
• Partnership (ห้างหุ้นส่วน) — Simpler structure for smaller operations. Thai partner must hold majority
• Sole Proprietorship — Only available to Thai nationals

Compliance Requirements

Record Keeping

All dispensaries must maintain:

• A log of every PT 33 prescription fulfilled, including patient name (or passport number for tourists), practitioner name, products dispensed, and quantities
• Inventory records with batch numbers and supplier information
• Financial records for tax reporting

Product Sourcing

• Cannabis flower must be sourced from licensed cultivators
• Products should have Certificates of Analysis (COA) from accredited laboratories
• THC content must be accurately labeled
• Imported cannabis products require separate import permits

Practitioner Requirements

Since June 2025, the following practitioners can issue PT 33 prescriptions:

1. Licensed physicians (แพทย์)
2. Dentists (ทันตแพทย์)
3. Traditional Thai Medicine practitioners (แพทย์แผนไทย)
4. Applied Thai Traditional Medicine practitioners (แพทย์แผนไทยประยุกต์)
5. Pharmacists (เภสัชกร)
6. Licensed traditional medicine practitioners (ผู้ประกอบวิชาชีพการแพทย์แผนไทย)
7. Veterinarians (สัตวแพทย์) — for animal treatment only

Inspections

FDA Thailand and local health authorities conduct periodic inspections. Common inspection points:

• Proper storage conditions
• PT 33 records accuracy
• Practitioner presence during operating hours
• Product labeling compliance
• Waste disposal procedures

Practical Steps to Open a Cannabis Business

Step 1: Legal Consultation

Engage a Thai attorney experienced in cannabis law. Do not proceed without legal advice specific to your situation and location.

Step 2: Business Registration

Register your company with the Department of Business Development. Obtain your tax ID from the Revenue Department.

Step 3: Secure Premises

Find a location that meets zoning requirements. Negotiate a lease with terms that align with your business plan.

Step 4: Hire a Licensed Practitioner

Recruit a pharmacist or TTM practitioner with cannabis medicine certification. This is non-negotiable for dispensary operations.

Step 5: Apply for License

Submit your license application to FDA Thailand with all required documentation. Processing times vary by license type and completeness of documentation.

Step 6: Set Up Compliance Systems

Implement record-keeping, inventory management, and PT 33 logging systems before opening.

Step 7: Source Products

Establish supply relationships with licensed cultivators and manufacturers. Verify COA documentation for all products.

Common Mistakes to Avoid

• Skipping legal consultation — Cannabis regulations change frequently. What was legal last month may not be legal this month.
• Nominee arrangements — Using Thai “nominees” for ownership is illegal and risks both criminal prosecution and loss of your entire investment.
• Operating without a practitioner — Even a temporary gap in practitioner coverage can result in license suspension.
• Ignoring zoning — Proximity restrictions to schools and temples are strictly enforced.
• Incomplete PT 33 records — Inspectors check prescription records. Missing or incomplete records are a common enforcement target.

CBD Business Opportunities

CBD products with less than 0.2% THC offer a lower-barrier entry into the cannabis market:

• No PT 33 requirement for sales
• Standard FDA food/cosmetic registration applies (depending on product type)
• Available through regular retail channels (pharmacies, wellness shops, online)
• Growing consumer demand, particularly for oils, skincare, and supplements

Costs Summary

Costs are estimates as of May 2026 and vary by location and business scope. The April 30, 2026 rules can push compliance setup costs higher — particularly for odor systems and dedicated storage.

Market Reality Check (May 2026)

Before investing, understand the current market conditions:

The Contraction

• 18,433 cannabis shops at peak → 11,136 still operating as of February 2026
• 8,636 licenses expired in 2025; only 1,339 (15.5%) renewed
• 4,587 more licenses expire in 2026; 5,210 in 2027
• Over 7,000 shops have closed since the June 2025 regulatory changes

What This Means

The market is consolidating around compliant, well-capitalized operators. Shops that could not afford licensed practitioners or did not transition to the medical model have closed. This creates opportunity for serious operators — less competition, established demand — but also means the easy-money era is over.

Most Viable Business Models in 2026

1. Medical dispensary with on-site clinic — Combined consultation and product sales in one location
2. CBD wellness brand — No PT 33 requirement, broad retail distribution, growing demand
3. Cannabis processing/manufacturing — Higher margins than retail, fewer but larger competitors
4. Wholesale distribution — Connecting farms with dispensaries. See our wholesale guide
5. Cannabis cultivation — For those with agricultural expertise. See our farming guide
6. Cannabis tourism — Farm tours, educational experiences, wellness retreats

Tax Obligations

Cannabis businesses are subject to standard Thai corporate and personal tax obligations:

• Corporate income tax — 20% on net profits for Thai limited companies
• VAT — 7% on sales (if annual revenue exceeds THB 1.8 million)
• Withholding tax — On employee salaries, contractor payments, and dividends
• Personal income tax — For sole proprietors and partnership income
• Social Security contributions — For all registered employees

Cannabis products are not currently subject to excise tax (unlike alcohol and tobacco), though this could change under the Cannabis and Hemp Act.

Insurance and Liability

Recommended insurance for cannabis businesses:

• General liability — Protects against customer injury claims
• Product liability — Essential for manufacturers and dispensaries
• Property insurance — Covers inventory, equipment, and premises
• Professional indemnity — For practitioners providing medical consultations
• Business interruption — Coverage if forced to close temporarily
