Evidence

More corroborating evidence would be helpful. Farsalinos, Konstantinos E., and Gene Gillman. "Carbonyl emissions in e-cigarette aerosol: a systematic review and methodological considerations." Frontiers in physiology 8 (2018): 1119. (emissions substantially lower than cigarettes. Unable to compare studies. Didn't look at effect on health, just emissions.). Hess, I. M., Kishen Lachireddy, and Adam Capon. "A systematic review of the health risks from passive exposure to electronic cigarette vapour." Public Health Res Pract 26.2 (2016): e2621617. (No meta analysis. 16 studies. EC vapour has the potential to lead to adverse health effects. The risk from being passively exposed to EC vapour is likely to be less than the risk from passive exposure to conventional cigarette smoke).
Health risks from passive vape not been extensively researched. more studies needed.
