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).

VCU Tests Nearly 1,300 School-Confiscated Vapes, Finding Mislabeling, Mixed Cannabinoids and Contamination
New research from Virginia Commonwealth University (VCU) found microbial contamination — including coliform, a bacteria indicating fecal exposure — in some vaping devices confiscated from U.S. schools. However, researchers stressed that newly purchased, unopened vapes showed no such contamination. The findings point to risks linked to unregulated products and improper storage conditions, reinforcing the importance of regulated supply chains and product authentication.
