About The Study: In this cross-sectional study of U.S. children, nicotine absorption was much lower in children who were exposed to secondhand vapor versus secondhand smoke, but higher than in those exposed to neither. These findings suggest that switching from smoking to vaping indoors may substantially reduce, but not eliminate, children’s secondhand exposure to nicotine and other noxious substances.
