So you’d figure that if your kids are growing up in a non-smoking household, their exposure to secondhand smoke will be pretty minimal, right?
Think again. Researchers at the Harvard School of Public Health have found that children who are raised in smokefree homes and live in smokefree communities have less cotinine – a byproduct of cigarette smoke - in their blood kids who live in smokefree homes but live in communities without smokefree laws.
The children who lived in both smokefree homes and counties with smokefree laws had 39 percent less cotinine in their blood than their counterparts who lived in counties without smokefree laws.
