Secondhand smoke from tobacco is worse than that from vaping Children exposed to indoor vaping absorb less than one-seventh the nicotine as kids exposed to indoor smoking Tobacco smoke likely exposes kids to more toxins and carcinogens as well FRIDAY, July 12, 2024 (HealthDay News) -- Secondhand smoke from cigarettes is much worse than that from , in terms of exposing children to nicotine, a new study finds. Children exposed to vaping indoors absorb less than one-seventh the amount of nicotine as kids exposed to indoor smoking, blood tests reveal. Secondhand exposure to harmful substances in e-cigarettes likely would be even lower, researchers said, given that vaping contains similar levels of nicotine but only a fraction of the toxins and carcinogens found in tobacco smoke.
“This paper suggests that concerns about secondhand vaping may be somewhat overstated, with second-hand exposure to toxic substances likely to be very low,” senior researcher , a professor of health psychology with the University College London Institute of Epidemiology and Health Care, said in a news release. “The findings confirm the risks of smoking indoors around children, which should be avoided at all costs,” Shahab continued. “However, as secondhand vaping still exposes children to more harmful substances than no vaping or smoking exposure at all, it is best to avoid indoor vaping around children, too.
” For the study, researchers analyzed blood tests for nearly 1,800 U.S. children ages .
