Washington D.C.: A recent study claims that smoking during pregnancy can have negative health impacts. According to researchers smoking during pregnancy can result in low birth weight, delayed intrauterine development, preterm birth, infant mortality, and long-term developmental delays. The details were published in the Journal of JAMA Network Open.

"Of concern, though, given the substantial benefits of smoking cessation during pregnancy, is the proportion of pre-pregnancy smokers who quit smoking during pregnancy has remained essentially stagnant since 2011," explains lead author Samir Soneji.
