Does the BOI promote cannabis businesses?

Foreign investors looking at Thai cannabis often ask the same question early: can the Board of Investment help? BOI promotion brings tax holidays, duty relief and, for promoted activities, permission for foreign ownership that the Foreign Business Act would otherwise restrict. For cannabis, the short answer is no, not as cannabis. The longer answer depends on what part of the value chain you mean.

What the BOI list says

The BOI publishes the activities eligible for promotion in its investment promotion guide. The 2025 guide names no activity for cannabis or hemp. Verified It does list activities that sit near parts of a cannabis value chain:

• Manufacture of natural extracts, on condition that the products are registered as herbal products or equivalent with the Thai FDA.
• Manufacture of active pharmaceutical ingredients and medicines, with GMP certification.
• Traditional or applied Thai medical services, on condition that the project holds a health establishment licence.

Whether a project that uses cannabis inputs fits one of these is a BOI decision, case by case. Nothing in the guide says it will. Estimated

What BOI promotion cannot fix

• Cannabis licences still apply. A promoted company still needs the DTAM licence for flower, the extract production licence for extracts and Thai FDA registration for finished products.
• Extracts are closed to foreign businesses. The extracts regulation in force since 25 April 2026 closed extract production, import and export to foreign businesses. Verified
• Retail is not on the list. The guide lists no retail activity, so a dispensary is not promotable on the published list.
• Nominee structures stay illegal. Section 36 of the Foreign Business Act makes nominee holding an offence for both the Thai holder and the foreigner. See the nominee trap.

Where BOI may still matter

For an investor building something adjacent to cannabis, such as a GMP medicine plant, a herbal products line or a Thai traditional medicine service, BOI promotion may be worth exploring on its own terms. Treat cannabis as one input among several, not the basis of the application, and confirm with the BOI and Thai counsel before you commit. See can a foreigner own a cannabis business in Thailand.
