Cannabis Marketing Laws in Thailand: The Complete 2026 Compliance Guide

If you run a cannabis business in Thailand, marketing is one of the most legally treacherous areas you’ll navigate. Since the June 2025 reclassification of cannabis flower as a controlled herb, Thailand has imposed a near-total ban on cannabis advertising — and violations carry real penalties, including imprisonment.

This guide breaks down exactly what the law says, what it means for your business, and what marketing channels remain available in 2026. Every claim here is sourced from official Thai government notifications, the Royal Gazette, and established Thai legal firms.

The Legal Foundation: Ministerial Notification B.E. 2568

Thailand’s cannabis marketing laws are not governed by a single comprehensive Cannabis Act. The proposed Cannabis and Hemp Act has been stalled in parliament since November 2024 and remains unpassed as of March 2026. Instead, the current regulatory framework is a patchwork of ministerial directives, with the most important being:

• Ministerial Notification Re: Controlled Herbs (Cannabis) B.E. 2568 — signed June 23, 2025 by Public Health Minister Somsak Thepsuthin and published in the Royal Gazette on June 26, 2025
• FDA Notification on Advertising Food B.E. 2564 — governs advertising of food products containing cannabis or hemp
• Cosmetic Product Act B.E. 2558, Chapter 6 — governs advertising of cosmetics containing cannabis or hemp
• Protection and Promotion of Thai Traditional Medicine Knowledge Act B.E. 2542 — the parent statute under which cannabis flower is now classified as a controlled herb

What Changed in June 2025

On June 25–26, 2025, cannabis flower was reclassified as a controlled herb under the traditional medicine framework. This was not a full re-listing as a narcotic (cannabis remains off Thailand’s narcotics schedule), but it fundamentally changed the rules:

• Recreational use is now explicitly prohibited
• Cannabis is available only for medical use with a valid prescription
• Prescriptions are limited to a maximum of 30 days and 30 grams per month
• Only 7 categories of licensed practitioners can prescribe cannabis (doctors, dentists, pharmacists, registered herbalists, and others)
• 15 pre-approved medical conditions qualify for cannabis prescriptions
• All cannabis must originate from DTAM-certified GACP cultivation sites

The impact on the industry has been severe. Of the 18,433 cannabis shops operating before June 2025, approximately 7,297 had closed by February 2026 — a 40% reduction.

Key Enforcement Agencies

Five agencies share authority over cannabis marketing enforcement:

Article 9: The Core Advertising Ban

Article 9 of Ministerial Notification B.E. 2568 is the single most important provision governing cannabis marketing. It imposes a comprehensive ban on both direct and indirect advertising across all media channels.

The Thai-language text states the prohibition in absolute terms: “การโฆษณากัญชา ห้ามเด็ดขาด ทุกรูปแบบ ทุกช่องทาง” — cannabis advertising is absolutely prohibited, in all forms, across all channels.

What Counts as Advertising Under Article 9

The ban covers every communication channel:

• Print media — newspapers, magazines, brochures, flyers
• Broadcast media — television and radio
• Digital media — websites, apps, online platforms
• Social media — Facebook, Instagram, TikTok, X (Twitter), YouTube
• Outdoor media — billboards, neon signs, banners
• Electronic sales channels — vending machines, e-commerce platforms
• Point-of-sale materials — promotional displays, branded merchandise used for advertising

Specifically Prohibited Activities

Based on Article 9 and related FDA regulations, the following marketing activities are explicitly banned:

1. All commercial advertising of cannabis products through any communication channel
2. Therapeutic benefit claims — even for products targeting medical use, you cannot advertise health benefits to the general public
3. Online sales — all e-commerce of cannabis products is prohibited
4. Celebrity endorsements — using famous persons to promote cannabis
5. Influencer marketing that glamorizes cannabis or depicts it as a lifestyle product
6. Marketing targeting minors — anyone under 20 years old
7. Product promotion or pricing on Facebook and Instagram
8. Photos depicting smoking, cannabis buds, or consumption on social media
9. Certain hashtags — #weed, #420, and similar promotional tags
10. Flashy or overt public signage — signs must be modest and non-promotional
11. Claims that cannabis food/beverages have “relaxing and refreshing effects” — specifically prohibited by the FDA
12. Inter-provincial delivery advertising — all transactions must be face-to-face at licensed premises

Prohibited Sales Channels

The advertising ban extends to a prohibition on sales through these channels, meaning marketing through them is also banned:

• Vending machines and automated dispensers
• E-commerce platforms and online stores
• Temples and religious sites
• Dormitories and student housing
• Public parks, zoos, and amusement parks
• Schools, universities, and educational settings

Penalties for Advertising Violations

Cannabis advertising violations in Thailand carry penalties under multiple legal frameworks, depending on the product type. Here is a consolidated breakdown:

Controlled Herb Violations (Traditional Medicine Act)

For violations related to cannabis flower classified as a controlled herb:

Cannabis Food Product Violations (FDA)

For advertising violations involving food products containing cannabis or hemp:

Cannabis Herbal Supplement and Cosmetic Violations

Drug Act Violations

Under Section 88(6) and Section 84 of the Drug Act, advertising dangerous or controlled drugs to the general public carries:

• Fine up to 100,000 THB and/or imprisonment up to 1 year

Administrative Penalties

Beyond criminal penalties, the Thai FDA can impose:

• Monetary fines per violation
• License suspension (up to 90 days per incident)
• License revocation (permanent, with a 2-year waiting period)
• Business closure orders

Enforcement Reality

The ONCB actively monitors both online and physical advertising. Since the June 2025 reclassification, enforcement actions have targeted dispensaries with overt signage, social media accounts promoting products with pricing, and businesses conducting online sales. The closure of approximately 7,297 shops by February 2026 reflects the seriousness of enforcement.

What IS Allowed: Legal Marketing Channels in 2026

Despite the comprehensive advertising ban, several marketing channels operate in a tolerated gray area. These activities are not explicitly authorized by law — they simply have not been explicitly banned or actively enforced against. Businesses use them at their own risk, but widespread adoption without enforcement suggests they are currently acceptable.

1. SEO and Organic Search Visibility

Search engine optimization remains the most effective legal marketing channel for cannabis businesses in Thailand. Because SEO involves making your website discoverable through organic search results rather than paid advertising, it falls outside the scope of Article 9.

What you can do:

• Optimize your Google Business Profile with accurate business information, hours, and location
• Create informational pages about your business on your own website
• Use local SEO tactics to appear in “near me” searches
• List your business on cannabis directory sites

2. Educational Content Marketing

Creating educational content about cannabis — its history, strains, quality identification, laws, and science — is generally tolerated. The distinction is between promoting cannabis products (banned) and providing information about cannabis (tolerated).

What works:

• Blog posts about cannabis strains and their characteristics
• Guides to understanding cannabis quality
• Legal explainers about Thailand’s cannabis regulations
• Educational videos on YouTube about cannabis cultivation or science
• Content using “learn more” language rather than sales-oriented messaging

What doesn’t work:

• Content that serves as thinly veiled product advertising
• “Educational” posts that include pricing or purchasing information
• Content making therapeutic claims about specific products

3. Google Business Profile Optimization

Your Google Business Profile is arguably the single most important marketing asset for a Thai cannabis dispensary. It allows you to:

• Appear in Google Maps searches
• Display your business name, address, phone number, and hours
• Collect and respond to customer reviews
• Post photos of your store interior and exterior
• Share basic updates (avoiding promotional language)

This is not considered advertising under Thai law — it is a business directory listing.

4. LINE Marketing: The #1 Compliant Channel

LINE is the dominant messaging platform in Thailand, and it has become the primary marketing channel for cannabis businesses. Because LINE messages are private, opt-in communications rather than public advertisements, they fall outside the scope of Article 9.

Compliant LINE marketing strategies:

• Age-verified customer groups (require verification before joining)
• Loyalty programs and repeat customer rewards
• Order coordination for in-store pickup
• Educational content sharing
• New strain notifications to opted-in customers
• Customer service and consultation

Important boundaries:

• Do not make therapeutic claims even in private messages
• Require age verification (20+) before adding customers to groups
• Keep messaging educational and informational rather than promotional

5. Email Marketing

Opt-in email marketing with proper age disclaimers is tolerated. The same principles that apply to LINE marketing apply here — private, opt-in communication with consenting adults is treated differently from public advertising.

6. Directory Listings

Listing your business on cannabis directory websites (such as Cannabis for Thailand, Weed.th, and ThaiWeedGuide) is a standard practice that has not been subject to enforcement. Directory listings are treated as informational rather than promotional.

7. In-Store Experiences

What happens inside your licensed premises is largely your domain:

• Private events for customers aged 20 and older
• In-store displays and menu boards
• Staff recommendations and consultations
• Loyalty cards and merchandise
• Branded items for existing customers (not distributed publicly as advertising)

8. B2B Marketing to Medical Practitioners

The one area where more traditional marketing approaches are permitted is business-to-business communication with licensed medical practitioners. Because cannabis is now a medical product requiring a prescription, marketing to the 7 categories of licensed prescribers follows pharmaceutical marketing rules rather than the consumer advertising ban.

9. Review Sites and User-Generated Content

Customer reviews on Google, Facebook, and cannabis-specific platforms are user-generated content, not business advertising. Encouraging satisfied customers to leave honest reviews is a legitimate marketing strategy.

10. Sponsorships and Media Partnerships

Sponsoring content in publications, cannabis blogs, or media outlets is another gray area that has seen adoption. The key is that sponsored content must be educational or informational rather than directly promotional of cannabis products.

The CBD and Low-THC Exception

Products derived from non-flower parts of the cannabis plant (leaves, stems, roots) and products with THC content under 0.2% of dry weight are classified as general herbal medicine, not controlled herbs. This creates a meaningful distinction for marketing purposes.

What This Means for CBD Marketing

CBD products that meet the 0.2% THC threshold face fewer marketing restrictions than controlled herb (cannabis flower) products. However, they are still subject to:

• FDA food advertising rules if classified as food products
• Cosmetics Act advertising rules if classified as cosmetics
• Herbal medicine advertising rules if classified as supplements
• The general prohibition on making therapeutic claims to the general public

What You Can Do with CBD Products

• Market them as food, cosmetic, or wellness products (within FDA guidelines)
• Include them in product lines alongside non-cannabis items
• Advertise them through channels that comply with FDA food/cosmetics advertising rules
• Sell them through e-commerce (the online sales ban applies specifically to controlled herbs)

What You Still Cannot Do

• Make health or therapeutic benefit claims to consumers
• Market them as “cannabis products” using cannabis imagery
• Target minors or vulnerable populations
• Bypass FDA product registration and labeling requirements

Social Media Compliance: Platform by Platform

Each social media platform presents different risks and opportunities for cannabis businesses in Thailand.

Facebook and Instagram (Meta)

Status: High risk

Meta’s own policies already prohibit cannabis advertising globally. Combined with Thailand’s Article 9 ban, Facebook and Instagram are the most dangerous platforms for cannabis marketing.

Absolutely prohibited:

• Product photos showing cannabis buds, flowers, or concentrates
• Pricing information or special offers
• Before/after claims or therapeutic testimonials
• Links to online ordering or delivery
• Cannabis-related hashtags (#weed, #420, #cannabis used promotionally)

What businesses do (gray area):

• Post photos of store interiors and ambiance (without visible products)
• Share educational articles about cannabis science or law
• Display plant leaf imagery (not buds or flowers)
• Use business page as an informational presence rather than sales channel

LINE

Status: Lowest risk — preferred channel

LINE’s private messaging model makes it the safest platform for cannabis business marketing in Thailand.

Best practices:

• Create an official LINE account with age verification
• Build customer groups for loyalty programs
• Share educational content and strain information
• Coordinate in-store pickups and consultations
• Use LINE’s CRM features for customer management

YouTube

Status: Medium risk

Educational cannabis content on YouTube is generally tolerated. YouTube’s own policies are more permissive than Meta’s for informational content.

What works:

• Strain review videos (educational, not promotional)
• Cannabis science and cultivation education
• Legal explainers about Thai cannabis law
• Store tour videos

Avoid:

• Direct product promotion with pricing
• Calls to action for purchasing
• Content depicting underage consumption

X (Twitter)

Status: Medium risk

X is the only major platform that has launched a certified cannabis advertising program, but this applies to specific markets (primarily the US) and does not override Thai law. Organic educational content is tolerated.

Google Ads

Status: Prohibited

Google’s advertising policies prohibit cannabis-related advertising globally. Do not attempt Google Ads campaigns for cannabis products. Focus on organic SEO instead.

TikTok

Status: High risk

TikTok’s community guidelines prohibit cannabis content, and Thailand’s Article 9 ban applies. TikTok’s algorithm-driven distribution also makes it harder to control who sees your content, increasing the risk of reaching minors.

Packaging, Labeling, and Signage Rules

Marketing compliance extends beyond advertising to how your products are packaged and your business is presented physically.

Product Packaging Requirements

Under MOPH Notification 425 (March 2021) and the controlled herb regulations:

Cannabis flower packaging must include:

• Plain, neutral design — no child-appealing elements
• THC and CBD content clearly displayed
• Warning labels stating that children, pregnant women, and nursing mothers should avoid the product
• “Read label warnings before consumption” notice
• All text in Thai and prominently visible
• Certificate of Analysis (COA) information — testing for heavy metals, pesticides, pathogens, and mycotoxins

Cannabis food product packaging must include:

• No images or symbols of any cannabis or hemp plant part
• “Food should be consumed as part of a balanced diet”
• Encouragement to consume from all five food groups
• “Product does not protect from and/or cure disease”
• THC content disclosure
• Species name or source for hemp seed products
• All required information in Thai

Storefront Signage Rules

What is permitted:

• Modest, understated business identification signs
• Business name and operating hours
• License number display (often required)

What is prohibited:

• Flashy neon signs with cannabis imagery
• Oversized cannabis leaf graphics
• Promotional messaging on exterior signage
• Images of buds, smoking, or consumption on signs
• LED boards displaying product menus visible from outside

How Thailand Compares to Other Markets

Understanding Thailand’s position relative to other regulated cannabis markets provides useful context.

Thailand vs. Canada

Canada permits licensed producers to advertise cannabis, albeit with heavy restrictions. Brand advertising, point-of-sale materials, and age-gated digital marketing are all legal in Canada. Thailand’s approach is far more restrictive — essentially a total advertising ban rather than regulated advertising.

Thailand vs. US State Markets

US states with legal cannabis (Colorado, California, Oregon, etc.) generally permit advertising with restrictions on targeting minors, making health claims, and advertising near schools. Many states allow billboards, digital advertising, and print ads with proper disclaimers. Thailand’s blanket ban is more restrictive than any US state market.

Thailand vs. Other Southeast Asian Countries

Thailand remains the only Southeast Asian country with any form of legal cannabis access. Neighboring countries — Myanmar, Laos, Cambodia, Malaysia, Singapore — maintain full prohibition. Thailand’s controlled medical-access framework, even with its advertising restrictions, represents the most permissive approach in the region.

What’s Coming Next: The Cannabis and Hemp Act

The proposed Cannabis and Hemp Act has been pending since November 2024. If passed, it would establish a comprehensive licensing and regulatory framework that could potentially include clearer rules for marketing and advertising. Key provisions of the draft bill include:

• A formal licensing system for cultivation, processing, and retail
• Potential penalties of 1–3 years imprisonment or 100,000–300,000 THB fines for unlicensed sales
• Clearer definitions of permitted and prohibited marketing activities

As of March 2026, the bill remains stalled. Businesses should not plan their marketing strategies around proposed legislation that may never pass. Comply with the current Ministerial Notification framework.

Key Takeaways

1. Article 9 of Ministerial Notification B.E. 2568 bans all cannabis advertising — direct and indirect, across all channels.

2. Penalties are real — up to 3 years imprisonment and 100,000 THB fines depending on the product type.

3. The safest marketing channels are SEO, LINE messaging, educational content, and Google Business Profile optimization — none of these are explicitly authorized, but they have not been subject to enforcement.

4. CBD products under 0.2% THC face fewer restrictions but are still subject to FDA advertising rules.

5. Packaging must be plain and in Thai with mandatory warning labels and THC content disclosure.

6. The comprehensive Cannabis and Hemp Act remains stalled — current law is a patchwork of ministerial directives.

7. When in doubt, err on the side of education over promotion. The line between information and advertising is not clearly defined in Thai law, but businesses that frame their marketing as educational have been far less likely to face enforcement.
