Secondhand smoke exposure at home may weaken teens' academic performance

According to a new study, teens who are exposed to secondhand smoke at home are at a very high risk of failing in a test at school.

Astonishingly, the study found that when the effects of prenatal tobacco exposure and secondhand smoke together were examined, prenatal exposure did not influence test performance anywhere.

However, the study did not reveal the reason for secondhand smoke influencing failure.

The study is published in the Journal of Adolescent Health.
