What is the current Thailand marijuana law?

Thailand allows medical use only. Recreational use is illegal again. Patients need valid prescriptions and must obtain products through licensed practitioners and authorized outlets. Shops that sold to tourists without medical checks are closing. Visitors should not buy or carry cannabis recreationally and should bring medical documentation if they rely on prescribed products.

Can Japanese tourists use medical cannabis in Thailand?

Yes, but only with a valid prescription recognized by Thai authorities and access through licensed medical channels. Tourists should not bring THC or CBD products across borders. Check with airlines and Thai officials before travel. Without proper documents, possession or use may lead to legal issues and trip disruptions.

Why did over 7,000 cannabis shops close?

Authorities shifted to a strict medical-only framework, re-criminalizing recreational use. Shops without proper medical licensing, prescription checks, or compliant sourcing faced shutdowns. Enforcement focuses on licensed practitioners, authorized outlets, and traceable products. Reports indicate closures exceeded 7,000 by February 4 as the rules took effect and inspections increased.

What should Japan-based investors watch next?

Monitor licensing rules, clinic approvals, and product testing standards. Track enforcement pace and any guidance from Thai health regulators. Rework 2026 forecasts toward medical channels and away from casual retail. Favor partners with strong compliance records, detailed documentation, and transparent supply chains that align with Thai medical cannabis rules.
