An analysis of data concerning more than 5,200 primary school students reveals that kids exposed to secondhand smoke while in the womb and/or at a young age have a greater risk for behavioral problems, especially emotional and conduct disorders. Study leader Dr. Isabella Annesi-Maesano wrties, “Our data indicate that passive smoking, in addition to the well-known effects on health, should also be avoided because of the behavioral disorders it may cause in children.”
