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).

$20 Million, a Permanent Injunction and Distributor Controls: Posh Deal Tightens Illinois Vape Compliance
An Illinois court ordered three companies tied to Posh vapes to pay $20 million and permanently restricted the sale, marketing and distribution in Illinois of products lacking required FDA authorization.

South Korea Constitutional Court Upholds Volume-Based E-Liquid Tax, With Challenged Rates at KRW 370 and KRW 628 per Milliliter
South Korea Constitutional Court Upholds Volume-Based E-Liquid Tax, With Challenged Rates at KRW 370 and KRW 628 per Milliliter
South Korea's Constitutional Court has upheld fixed taxes on nicotine-containing e-cigarette liquids based on solution volume, ruling that challenged provisions imposing KRW 370 per milliliter in individual consumption tax and KRW 628 per milliliter in tobacco consumption tax do not violate the Constitution. The cases stemmed from historical disputes involving importers that reported nicotine as being extracted from tobacco stems rather than leaves. South Korea has since broadened its tobacco definition to include synthetic nicotine, while current tax laws provide reduced rates for certain products not derived from tobacco.

The Global State of Tobacco Harm Reduction, a project operated by Knowledge·Action·Change, estimates that about 200 million people worldwide use non-combustible nicotine products including vapes, heated tobacco, nicotine pouches and snus. Its 2026 report says use of these products rose alongside declining smoking rates in 28 countries it analyzed. The data do not establish that all 200 million users have quit smoking, nor do they prove a direct causal relationship. GSTHR also says regulatory restrictions on the products continue to expand in many markets.
