Smoking Facts

PSF babySmoking during pregnancy causes great health risks to both mother and child and is considered the single most important and changeable risk factor for improving health outcomes. Despite the well-documented health effects of smoking during pregnancy, approximately 11 percent of women in the U.S. smoke during their pregnancy.

The rates of spontaneous or recent quitters, women who smoked prior to conception and quit after learning they were pregnant, range from 25 to 60 percent. Many recent quitters relapse during pregnancy or postpartum, either because they never intended to stay quit or because their mentality changes and they give themselves permission to smoke again.

Data from the National Health Interview Survey indicate that 27 percent of children under the age of six live in a house where someone smokes inside at least four days per week. While most people are aware that smoking while pregnant can harm the unborn baby, it is important to point out that smoking and smoke in the environment lead to many health complications for the mother and the baby both before and after birth.
