- Children exposed to secondhand tobacco smoke, secondhand vapor, or neither were compared for nicotine absorption in a recent study.
- The study found that children exposed to secondhand tobacco smoke had the highest nicotine absorption, followed by those exposed to secondhand vapor, and those with no exposure had the lowest absorption.
- Exposure to secondhand vapor only resulted in 84% lower nicotine absorption compared to exposure to secondhand tobacco smoke, while children with no exposure had 97% lower absorption.
- Adjusting for demographic and socioeconomic factors, the differences in nicotine absorption remained significant among the three groups.
- This study highlights the importance of avoiding vaping around children, as it can still result in higher levels of secondhand nicotine exposure, although lower than exposure from smoking.
