How safe are the individuals who are close to someone who is vaping? This question goes straight to the heart of the debate regarding the extent to which vaping is safer than smoking combustible cigarettes. Research has shown that the vapor that escapes into the atmosphere while someone is using an electronic cigarette doesn’t contain any combustion toxicants. However, the study found that people who were near the person vaping were exposed to some nicotine in the vapor. This is particularly noticeable indoors. The implication of these findings is that vulnerable people, such as the elderly and young children, need to be protected from this secondhand exposure to nicotine. Vapers should therefore take precautions when they are vaping indoors. Additional research also needs to be conducted about the possible impacts of that secondhand exposure to nicotine.
