Study reveals children exposed to second-hand e-cigarette vapour have 84% less nicotine than those exposed to traditional second-hand smoking.

A first-of-its-kind study reveals children exposed to second-hand e-cigarette vapour have 84% less nicotine in their systems compared to those exposed to traditional second-hand smoking. However, vaping still exposes children to nicotine and may present other risks. The study published in JAMA Network Open suggests that to keep children completely nicotine-free, people should avoid smoking or vaping around children.
