One cannabis mistake at airport could bring 10 years in prison and $15,000 fine

Thailand's new customs policy, effective June 2026, imposes up to 10 years in prison and a $15,000 fine for travelers caught with cannabis. The U.S. Embassy in Thailand warns that importing cannabis remains illegal despite Thailand's 2022 decriminalization of possession. Experts highlight the risk of severe penalties in countries with strict drug laws, citing WNBA star Brittney Griner's imprisonment in Russia as an example.
