e-cigarettes smoke may be less harmful than regular tobacco cigarettes

E-Cigarettes

Washington, Aug 29 : A new study conducted by USC has demonstrated that a second-hand smoke of e- cigarette has increased levels of certain toxic metals even if they were less harmful as compared to the regular cigarettes.

An electronic cigarette (e-cig or e-cigarette), personal vaporizer (PV) or electronic nicotine delivery system is abattery-powered vaporizer which simulates tobacco smoking by producing an aerosol that resembles smoke.

e-cigarette devices arose from an invention made in China in 2003 and devices are predominantly manufactured in China.

The study discovered an overall 10-fold decrease in exposure to harmful particles, with close-to-zero exposure to organic carcinogens.

According to hr study, e-cigarette smoke contained the toxic element chromium, absent from traditional cigarettes, as well as nickel at levels four times higher than normal cigarettes despite the lack of harmful organic material and a decrease in the majority of toxic metals emissions.

Constantinos Sioutas, professor at the USC Viterbi School of Engineering, said that their results showed that overall electronic cigarettes seem to be less harmful than regular cigarettes, but their elevated content of toxic metals such as nickel and chromium did raise concerns.

The study is published in the Journal of Environmental Science, Processes and Impacts.
