Ultrafine Particles in E-cigarettes 12x More Than Regular Cigarettes
A recent study by the Korea Disease Control and Prevention Agency found that e-cigarettes emit 12 times more ultra-fine particles than regular cigarettes.

A recent study by the South Korean Centers for Disease Control and Prevention found that ultrafine particles emitted by liquid electronic cigarettes are 12 times higher than those emitted by traditional cigarettes.


An analysis of chemical composition through emitted smoke and aerosol shows that liquid-based e-cigarettes release 172,845 micrograms (µg) of ultra-fine dust per 0.2 grams of liquid, which is 12 times more than what is emitted by traditional cigarettes.


Meanwhile, heating tobacco emits 3100 micrograms of ultrafine particles per cigarette, which is lower than the emissions from regular cigarettes.


Within three minutes, the ultra-fine particles emitted by liquid e-cigarettes can spread up to 10 meters, while the range for traditional cigarettes is between 6 to 7 meters and 3 meters for regular cigarettes.


The study also revealed that chemicals similar to car exhaust emissions, such as black carbon, are released by all three types of tobacco.


The highest level of black carbon is found in regular cigarettes, followed by liquid electronic cigarettes (98.8 micrograms per unit) and heated tobacco (11.41 micrograms per unit).
