Is It Legal to Start a Cannabis Business in Thailand?

Yes, it is legal to start a cannabis business in Thailand, but only within the medical-only framework, with the correct licenses, and, for foreigners, within the 49 percent ownership cap. Recreational cannabis businesses are illegal since June 2025. The legal opportunity is real but narrower and more regulated than the 2023 gold rush suggested.

What kind of business is legal

Legal cannabis businesses now operate on the medical model: licensed dispensaries with on-site medical supervision, licensed cultivation, compliant product manufacturing within the rules, and supporting services. What is not legal is a recreational retail model, which the reclassification ended. Any plan built on recreational sales is a plan for an illegal business.

The licensing reality

Starting up means obtaining the licenses appropriate to your activity, meeting the compliance requirements that have tightened through 2025 and 2026, including the January 2026 on-site practitioner rule for dispensaries, and sourcing from certified suppliers. This is a filter. It is also why the surviving businesses tend to be better-capitalized and more serious than the ones that closed.

For foreign founders

A foreigner can start a cannabis business, but must respect the ownership cap and structure genuine Thai-majority control, avoiding the nominee trap. The businesses that work are built as compliant, properly structured ventures from the start. The ones that fail usually cut corners on structure or underestimate the compliance burden.
