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).

Science | International Experts Propose a New Smoking Cessation Pathway, Citing Higher Quit Rates With E-Cigarettes Than Nicotine Replacement Therapy
Science | International Experts Propose a New Smoking Cessation Pathway, Citing Higher Quit Rates With E-Cigarettes Than Nicotine Replacement Therapy
A new expert paper in JAMA urges U.S. clinicians to include nicotine e-cigarettes in smoking-cessation discussions, citing higher quit rates than nicotine replacement therapy. It also stresses that products must deliver enough nicotine to replace cigarettes, dual use should be brief, and complete switching is the goal. 2Firsts argues the recommendations matter beyond clinics: public-health professionals should reassess relative risk, regulators should preserve sufficient product appeal for adult smokers, and manufacturers should focus on helping users quit cigarettes more sustainably.
