Electronic cigarettes are battery-powered devices that heat up liquid and turn it into an aerosol vapor that can be inhaled.
E-cigarettes are loaded with a nicotine-based liquid are potentially as harmful as unfiltered cigarettes when it comes to causing DNA damage.
The researchers also found that vapor from non-nicotine e-cigarettes caused as much DNA damage as filtered cigarettes, due to chemical additives present in e-cigarette vapors. Cellular
mutations caused by DNA damage can cause cancer.
The amount of vapor the user inhales will determine the level of DNA damage e-cigarette can cause.
