A study has found that toxins in e-cig vapor can exceed set limits, but secondhand exposure under certain circumstances is likely to cause less harm than breathing in others' cigarette smoke.
Exposure to toxins in e-cig vapor varies depending on scenario
E-cigarettes are often perceived to be less harmful than their traditional counterparts, but they could still expose the people who "vape" and those around them to harmful compounds. Researchers now report in ACS' journal Environmental Science & Technology that heavy use and secondhand emissions could lead to inhaled levels of toxins that exceed set exposure limits. But under typical use, secondhand exposure would have a lower impact on health than second- and third-hand cigarette smoke.
