Smoking during pregnancy puts both mother’s and baby’s life at risk. Currently, about 13 percent of pregnant women in the U.S. smoke during pregnancy. If all pregnant women stopped smoking, there would be an estimated 10 percent reduction in infant deaths in this country, according to the U.S. Public Health Service. Cigarette smoke contains more than 2,500 chemicals, with nicotine, tar, and carbon monoxide thought to be the most dangerous to the fetus.

How Smoking Can Harm the Baby

Smoking nearly doubles a woman’s risk of having a low-birthweight baby. In 2002, 12.2 percent of babies born to smokers in the United States were of low birthweight (less than 5½ pounds), compared to 7.5 percent of babies of nonsmokers.2 Low birthweight can result from poor growth before birth, preterm delivery or a combination of both. Smoking has long been known to slow fetal growth. Studies also suggest that smoking increases the risk of preterm delivery 37 weeks of gestation). Premature and low-birthweight babies face an increased risk of serious health problems during the newborn period, chronic lifelong disabilities (such as cerebral palsy, mental retardation and learning problems) and even death.

Smoking After Birth

It’s also important to stay smoke-free after you bring your baby home. Both mother and father should refrain from smoking in the house, and insist that visitors to do the same.

Babies who are exposed to cigarette smoke after birth face an increased risk of SIDS. They also suffer from more respiratory illnesses, ear infections, and tonsillitis than other babies. According to the AAP, an estimated 1.67 million physician visits each year in the United States are to treat coughing due to involuntary smoking. Infants whose mothers smoke are 38 percent more likely to be hospitalized for pneumonia during their first year of life than babies of nonsmoking mothers.

Smoking in the home during the first few years of a child’s life also increases his risk of developing asthma. Continual smoking can lead to more frequent and severe asthma attacks in children who already have the disease.

Nursing mothers who smoke more than 20 cigarettes a day will likely pass along harmful chemicals from cigarettes to their babies in breast milk. Heavy smoking can reduce a mother’s milk supply, and on rare occasions has caused symptoms in the breastfeeding baby such as nausea, vomiting, abdominal cramps, and diarrhea.
