Most women do not smoke during pregnancy. That’s a good thing. Even better, the CDC says the small number who do has shrunk by more than a third. Smoking is a major risk factor for poor pregnancy outcomes and health problems for newborns later in life.
Among pregnant women who continued to smoke, the CDC said they tended to be under the age of 30 and live in these 10 states: Arkansas, Kentucky, Maine, Missouri, Montana, Ohio, South Dakota, Vermont, West Virginia and Wyoming.
