A 31-year-old Thai woman was arrested in Japan for allegedly smuggling etomidate—commonly referred to as “zombie cigarettes”—into the country via Kansai International Airport, marking the first etomidate-related enforcement case at the airport since the drug was added to Japan’s controlled substances list in May last year. Osaka Customs said the suspect allegedly brought 1,002 cartridges containing about 500 grams of etomidate from Thailand in November, concealing them inside seven snack packets in her suitcase. She was traveling with a Malaysian man who was also arrested and indicted on separate charges for allegedly smuggling stimulants into Japan.

Thailand Finding Rise of Narcotic-Laced Vapes
Thailand’s Department of Medical Sciences (DMS) warned that e-cigarettes are increasingly being laced with etomidate, a short-acting anesthetic that poses serious risks to the brain, respiratory system, and other vital organs. Tests conducted between October 2024 and June 2025 found etomidate in 56 of 83 e-cigarette and equipment samples. The Thai Food and Drug Administration (FDA) classified etomidate as a Special Controlled Drug before elevating it to a Schedule 2 Psychotropic Substance on July 27, to enforce stricter importation and usage rules. Despite this, the anesthetic has been detected in e-cigarettes produced in Asia and in smuggled e-liquids entering Thailand.
Reports indicate that etomidate is being mixed with or substituted for nicotine in modified e-cigarettes known as “Zombie Cigarettes” or “Pot K.” The DMS has developed a testing method to detect the substance, which will aid police in drug suppression efforts. Authorities have also found e-cigarettes laced with narcotics such as cocaine and fentanyl, raising concerns about increased fatality risks among users.
