This article The Surgeons General's Report on Secondhand Smoke:
"The health effects of secondhand smoke exposure are more pervasive than we previously thought," Carmona said in his report. "The scientific evidence is now indisputable: Secondhand smoke is not a mere annoyance. It is a serious health hazard that can lead to disease and premature death in children and nonsmoking adults." This is a bold claim, but the evidence backs up Carmona.
Children are especially vulnerable. Because they are still developing physically and tend to have higher breathing rates -- and, in turn, higher quantities of smoke entering their bodies -- children are especially at risk around secondhand smoke. According to the Environmental protections agency, secondhand smoke will:
Increase the number of asthma attacks and severity of symptoms in 200,000 to 1,000,000 children with asthma. Cause between 150,000 and 300,000 lower-respiratory-tract infections among children (under 18 months of age). Be responsible for respiratory-tract infections that result in 7,500 to 15,000 hospitalizations of children each year.
