Bhumjaithai Party Advances Cannabis Control Bill in Thailand

Bhumjaithai Leads Regulatory Push Two Years After Decriminalization

Thailand's ruling Bhumjaithai Party introduced a comprehensive cannabis control bill to parliament on July 5, 2026, seeking to resolve regulatory ambiguities that have persisted since the 2022 decriminalization. The party, led by Deputy Prime Minister and Public Health Minister Anutin Charnvirakul, campaigned on cannabis liberalization in 2019 and oversaw the June 2022 removal of cannabis from Thailand's Category 5 narcotics list.

The 2022 decriminalization didn't establish a licensing framework or product standards. Businesses have operated under interim Public Health Ministry guidelines that lack statutory force.

Core Provisions: Licensing, Age Gates, and THC Thresholds

The bill would mandate licenses for cultivation, processing, and retail distribution, with age restrictions barring sales to individuals under 20. The draft text establishes three license tiers:

• Cultivation permits for growers producing cannabis for medical, industrial, or regulated adult use
• Processing licenses for manufacturers extracting cannabinoids or formulating products
• Retail permits for dispensaries and licensed points of sale

THC content in consumer products would be capped at levels determined by ministerial regulation. Edibles, beverages, and cosmetics containing cannabis would require separate product registration with the Food and Drug Administration.

Regulatory Gap Since June 2022 Created Compliance Uncertainty

Since decriminalization in June 2022, Thailand's cannabis sector has grown without clear statutory guardrails. Operators remain uncertain about compliance obligations. The Public Health Ministry issued guidelines in 2022 restricting recreational use and requiring businesses to register, but these directives lack enforcement mechanisms under Thai administrative law.

An estimated 6,000 cannabis dispensaries opened across Thailand between June 2022 and December 2025, according to industry trade groups. Many sell high-THC flower and extracts marketed as wellness products. They're operating in a regulatory void.

Opposition Parties Seek Stricter Controls or Re-Criminalization

Opposition parties, including Pheu Thai and the Democrat Party, have called for tighter restrictions or a full reversal of the 2022 decriminalization. Pheu Thai lawmakers introduced competing legislation in early 2026 that would limit cannabis use to medical purposes only and re-classify recreational products as controlled substances.

The Bhumjaithai bill faces committee review and floor debate in the National Assembly. Passage requires a simple majority in both the House of Representatives and the Senate.

The Bhumjaithai proposal represents a middle path between full prohibition and the current unregulated market, but its success depends on coalition support in a fragmented parliament.

Revenue Implications: Tax Structure Remains Undefined

The bill doesn't specify excise tax rates or revenue-sharing formulas between central and local governments. Thailand's Excise Department hasn't issued guidance on cannabis taxation since the 2022 decriminalization. Industry observers expect the final legislation to include a per-gram excise tax on flower and a percentage-of-sale tax on processed products, similar to the structure applied to alcohol and tobacco.

Without defined tax rates, operators can't model post-legalization cost structures. The absence of a tax framework in the current draft suggests that implementing regulations will follow statutory enactment, a common pattern in Thai administrative law.

International Context: Thailand's Regional Leadership at Stake

Thailand was the first Southeast Asian nation to decriminalize cannabis, positioning itself as a regional hub for medical cannabis research and cultivation. Neighboring countries, including Malaysia and the Philippines, have since expanded medical cannabis programs, creating competitive pressure on Thailand to formalize its regulatory regime.

The delay in enacting comprehensive legislation has slowed foreign investment in Thai cannabis ventures. International pharmaceutical companies and agricultural investors have cited regulatory uncertainty as a barrier to capital deployment.

Next Steps: Committee Review and Coalition Negotiations

The bill will move to the House Committee on Public Health for markup and stakeholder testimony before returning to the floor for a second reading. Bhumjaithai holds 71 seats in the 500-member House of Representatives. It relies on coalition partners to reach the 251-vote threshold for passage.

Final passage timeline hinges on coalition negotiations and the volume of amendments introduced during committee review. Thai legislative procedure allows for three readings before a bill advances to the Senate. We'll be watching for committee markup language on THC caps and local licensing authority, both of which remain undefined in the current draft.
