Second-hand smoke tied to children's behavior problems

(All smokes from  fire are toxic fumes---whether from tobacco, pot, or whatever; makes no difference. They are all toxic and harmful---no such thing as "harmless" fume)

NEW YORK, July 14 (Reuters Life!) - Children exposed to secondhand smoke at home may be more likely to have learning and behavioral problems, according to a U.S. study.

Of more than 55,000 U.S. children younger than 12 years, 6 percent lived with a smoker -- and those children were more likely to have ADHD compared to children in smoke-free homes, the study, published in Pediatrics, found.

Even after accounting for a number of possible explanations, such as parents' income and education levels, secondhand smoke was still tied to a higher risk of behavioral problems, said Hillel Alpert at the Harvard School of Public Health, one of the researchers.
