Taiwan Escalates Etomidate to Category 1 Narcotic as Drug-Impaired Driving Cases Surge
Key Insights
Taiwan reclassified etomidate as a Category 1 narcotic on June 27, 2026, making the death penalty the maximum punishment for its manufacture, transportation, and sale.
Drug-impaired driving cases in Taiwan surged from 2,619 in 2024 to 8,659 in 2025, with etomidate detected in approximately 20% of drivers in 2026.
Etomidate-related deaths reached 92 in 2025, the highest among all new psychoactive substances, accounting for roughly 60% of such fatalities.
Taiwan's Ministry of Justice Investigation Bureau (search) has raised alarm over the rapid proliferation of etomidate abuse, driven largely by its integration into e-cigarette products, as the government escalates legal responses to what officials describe as a growing threat to public safety.
The National Police Agency (search) (NPA) recorded 8,659 cases of drug-impaired driving in 2025, a sharp increase from 2,619 cases in 2024. Between January and May 2026 alone, authorities had already documented 6,730 such cases. Of the cases recorded in 2026, approximately 20% involved drivers who tested positive for etomidate, second only to methamphetamine at 75% and followed by ketamine at 15%. The percentages exceed 100 because some drivers tested positive for multiple drugs.
Rapid Spread Driven by Low Cost and Vaping
Lee Chia-ning, an officer with the bureau's Drug Enforcement Division, explained that etomidate has spread quickly because it is inexpensive, fast-acting, and easy to consume through vaping devices. Unlike many traditional drugs, which are often used in fixed locations and primarily harm users and their families, etomidate can be consumed almost anywhere, including inside vehicles, increasing the risk to the general public.
"Etomidate is chemically synthesized rather than cultivated and processed like drugs such as marijuana or heroin, making it relatively inexpensive to produce," Lee said. While the drug takes effect in about 10 seconds when injected, it can also be easily mixed into e-cigarette liquids and inhaled, producing effects within 10 to 60 seconds. Drivers who use the drug may suddenly experience muscle rigidity or involuntary twitching, posing a serious traffic safety risk.
According to government anti-drug information, etomidate users can lose the ability to think clearly or control their movements and may experience abnormal tremors or become unable to speak, bend forward at the waist, and twist their bodies uncontrollably.
Escalating Public Health Impact
Citing bureau data, Lee noted that etomidate first appeared in Taiwan in 2023 and spread rapidly along with the growing popularity of vaping. The market expanded during a legislative gap before the drug was classified as a Category 3 narcotic in August 2024, and it was subsequently upgraded to a Category 2 narcotic in November of that year.
Statistics from the Ministry of Health and Welfare showed that 8,897 urine tests were positive for etomidate in 2025, roughly 11 times the 806 recorded in 2024. The number of samples subject to different tests that tested positive reached 31,507, up from 8,403 a year earlier.
The Ministry of Justice reported that etomidate-related deaths rose to 92 in 2025, the highest among all new psychoactive substances, accounting for about 60% of such fatalities.
Enforcement Challenges
According to the NPA, police seized 40,610 drug-laced e-cigarette cartridges in 2025, up 117% from 18,687 in 2024. As of April 2026, authorities had seized a cumulative 849.5 kilograms of etomidate since the drug came under regulation in 2024, equivalent to roughly 8.5 million etomidate-laced vape cartridges.
Chen Chien-yu, acting captain of the Taipei City Police Department Criminal Investigation Division's Narcotics Center, said that drug-laced vape cartridges are virtually indistinguishable from ordinary cartridges and lack the distinctive odor associated with drugs such as ketamine, making them much harder for police to detect.
He added that new psychoactive substances such as etomidate are often manufactured using precursor chemicals that have yet to be regulated and are inexpensive, making them particularly attractive to teenagers. Lee further warned that vape cartridges can be mixed with various narcotics and flavored in numerous ways, making them appear trendy and encouraging experimentation among students. "Many young people may be persuaded by friends or drug dealers to unknowingly consume etomidate through vaping without intending to take drugs," Lee said.
Tougher Legal Penalties
In response to the escalating crisis, etomidate was reclassified as a Category 1 narcotic on June 27, 2026, making the death penalty the maximum punishment for the manufacture, transportation, and sale of the drug. Its precursor chemicals, including Etomidate Acid and Ethyl N-formyl-N-(1-phenylethyl)glycine, have also been designated Category 4 narcotic precursors, making their manufacture, transportation, and sale subject to criminal penalties, Deputy Justice Minister Huang Mou-hsin said.
On June 11, the Cabinet approved draft amendments to the Criminal Code that would impose heavier penalties for drug-impaired driving. The Ministry of Justice has also proposed amendments introducing saliva-based drug testing to improve enforcement. Separately, the Cabinet has proposed stricter penalties for e-cigarette use that would also penalize possession of such products, which are banned in Taiwan.
