How many children are born a year with birth deffects from smoking mothers?

While the exact number of children born with birth defects specifically due to maternal smoking can vary by region and year, studies estimate that around 10% of birth defects may be linked to maternal smoking. In the United States, this translates to thousands of cases annually, as approximately 10-15% of pregnant women smoke. The risks include low birth weight, preterm birth, and various congenital anomalies. Public health initiatives continue to emphasize smoking cessation during pregnancy to reduce these risks.
