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).

Pennsylvania Vape Directory Law Survives Court Challenge From Nova Distro and Others Amid Similar Rulings Across States
Pennsylvania Vape Directory Law Survives Court Challenge From Nova Distro and Others Amid Similar Rulings Across States
A U.S. federal court upheld Pennsylvania's vape directory law on October 14, rejecting a challenge brought by Nova Distro, 101 Distributors and companies operating Tobacco Hut retail stores. Court records show that vaping accounts for about 60% of Tobacco Hut's profits and that the chain held approximately $2 million in inventory potentially subject to seizure under the law as of June 2. Pennsylvania began enforcement on October 19. The ruling follows similar appellate decisions in other states, even as new research shows that unlisted vaping products continue to account for substantial sales in states with established directories.

JAMA Study: U.S. Vape Directories Fail to Sustainably Curb Unlisted Sales as Product Shifts May Redistribute Brand Share 2Firsts Recommended
A study by CDC Foundation researchers found no sustained decline in e-cigarette sales across Alabama, Oklahoma and Louisiana, the first three U.S. states to implement e-cigarette directory laws. Louisiana initially saw a significant sales decline, followed by a rebound and a persistent reduction in product availability. Sales also shifted from nontobacco-flavored disposables toward prefilled cartridges, with Vuse Alto driving much of the increase in menthol cartridges. By April 2025, unlisted products still accounted for more than half of e-cigarette nicotine sales in all three states.
