After Flight Attendant Heroin Bust: Thailand Orders Tougher Airport Drug Screening

On June 17, 2026, Thailand started classifying cannabis flowers as an offense under the country's Customs Act. In other words, anyone caught importing, exporting, or trying to circumvent cannabis restrictions could be sentenced to up to 10 years in prison, a fine of up to $14,800, or both.

Today, July 20, the country's Customs Department has ordered intensified inspections at all international airports, particularly focusing on high-risk flights as a means of stepping up its efforts to combat international drug smuggling

According to an announcement from the Public Relations Department of Thailand, customs officials have been instructed to strengthen screening procedures and improve coordination with security agencies as part of a nationwide initiative to prevent narcotics from entering or leaving the country.

The new measures are expected to increase the number of random inspections of passengers, as well as airline crew, and their luggage. The decision follows an incident at the end of June where Australian customs officers at Melbourne Airport allegedly discovered a Thai flight attendant was in the possession of one kilogram of heroin, valued at over 11 million baht ($327,000), allegedly smuggled into Australia.

A key part of the expanded security effort is taking place at Chong Chom Customs House, which oversees operations at Buriram Airport in northeastern Thailand. The airport handles more than 300,000 passengers annually and serves as an important regional gateway.

Officials said Chong Chom Customs House has strengthened cooperation with local law enforcement and other government agencies to improve monitoring and response capabilities. 

Thailand has long been a major transportation hub in Southeast Asia, making its airports critical points for customs enforcement. Authorities regularly conduct anti-drug operations, seizing narcotics ranging from methamphetamine and heroin to synthetic drugs destined for international markets.
