Children living with a smoker miss more days of school than those in smoke free homes, according to a new study.
Researchers say these children also have higher rates of respiratory illnesses often caused by second hand smoke.
Of the over three thousand children analyzed in the study, those living with one smoker were absent an average of one more day per year than those in non-smoking homes, while kids living with two or more smokers missed one and a half more days.
Second hand smoking has been shown to increase the number of ear infections and other upper respiratory conditions in children.
