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).

WIRED Investigation: Chinese-Made Vapes Turn to 6-Methyl-Nicotine and Other Analogs, Challenging U.S. Regulation
WIRED Investigation: Chinese-Made Vapes Turn to 6-Methyl-Nicotine and Other Analogs, Challenging U.S. Regulation
U.S. technology and investigative publication WIRED has examined how nicotine analogs are emerging as a new challenge for the country’s vape regulatory framework. The article argues that after the U.S. expanded federal oversight of nicotine products in 2022, some manufacturers began using nicotine-like compounds such as 6-methyl-nicotine that may fall outside existing definitions. Researchers cited by WIRED said some nicotine analogs could be more potent than traditional nicotine, although human health impacts remain unclear. U.S. policymakers are considering broader definitions of nicotine to bring these compounds under federal oversight.

FDA Proposes Foreign Tobacco Factory Registration Rule to Tighten Import Oversight
The FDA has proposed a rule requiring foreign tobacco manufacturers to register facilities and list products before exporting to the U.S. If finalized, the rule could affect overseas OEM/ODM factories, contract manufacturers, specification developers, bulk product makers, and repackaging or relabeling firms. FDA says the proposal would help identify unauthorized imported tobacco products, including e-cigarettes.
