Employers across the country are trying to figure out how e-cigs should be considered in the context of tobacco-free campus policies. The products do not produce smoke; they produce a vapor consisting of water, glycol, and nicotine. The dangerous tars that contain many toxins and carcinogens appear to be absent from e-cig vapor.
Analyses of e-cig vapor have yielded some minor concerns about low levels of toxins. A recent study found some toxins but reported that toxicant levels were up to 450 times lower than in cigarette smoke and comparable with trace amounts found in the Nicotine Inhaler, an FDA-approved quitting solution.
