Electronic cigarettes, also known as e-cigarettes, are devices designed to imitate regular cigarettes and deliver nicotine via inhalation without combusting tobacco. A study conducted by Tobacco Control found that the e-cigarette vapors contained some toxic substance; however, the levels of the toxicants were "9-450 times lower than in cigarette smoke and were, in many cases, comparable with trace amounts found in the reference product." Their study found that substituting tobacco cigarettes with electronic cigarettes may substantially reduce exposure to tobacco-specific toxicants.
