Liquid-based e-cigarettes emit 12 times more ultrafine dust than regular cigarettes, according to a recent study by the Korea Disease Control and Prevention Agency.

Liquid-based e-cigarettes emit 12 times more ultrafine dust than regular cigarettes: study

By photographing smoke and aerosols emitted from cigarettes to analyze their chemical composition, the results showed that liquid-based e-cigarettes emitted 172,845 micrograms (㎍) of ultrafine dust per 0.2 grams of liquid, 12 times more than what was emitted by non-electronic cigarettes.

 

Meanwhile, heated e-cigarettes emitted 3,100 ㎍ of ultrafine dust per cigarette, lower than emissions from non-electronic cigarettes.

 

Over a three-minute period, the ultrafine dust emitted by liquid-based e-cigarettes spread as far as 10 meters, heated e-cigarettes to between 6 and 7 meters and non-electronic cigarettes to 3 meters.

 

The study also revealed that black carbon, a chemical related to the automobile emissions stains, is released by all three types of cigarettes.

 

The highest black carbon levels were from non-electronic cigarettes, which were also present in liquid-based e-cigarettes (98.8 ㎍ per piece) and heated e-cigarettes (11.41 ㎍ per piece).

2Firsts Data | China’s Vape Exports Rise 3.1% in H1 2026 as 6-Methyl Nicotine-Related Products Surge 65.2%
2Firsts Data | China’s Vape Exports Rise 3.1% in H1 2026 as 6-Methyl Nicotine-Related Products Surge 65.2%
China’s vape exports showed resilience in the first half of 2026 after a short-term shock from China’s export rebate adjustment. But customs data points to more than a simple recovery: the structure of growth is changing. Vaping devices and atomization hardware emerged as the strongest growth driver, while nicotine-containing vaping products remained broadly stable. Meanwhile, nicotine substitute-related products represented by 6-methyl nicotine expanded rapidly, becoming a new category to watch for both industry and regulators. After the U.S. market went through a cycle of shortages, replenishment and inventory rebuilding in 2025, China’s vape supply chain is entering a new phase of reallocation.
