For moms-to-be trying to kick the smoking habit, using nicotine replacement therapy such as nicotine patches or gum, doesn’t increase the likelihood of stillbirths, according to a new study. While “smoking during pregnancy increases the risks of stillbirth, the use of nicotine replacement therapy (NPR) in pregnancy is a possible harm reduction strategy,” researchers from the University of Southern Denmark in Copenhagen write in the British Journal of Obstetrics and Gynecology this month.

Researchers admit there may be several explanations for the low risk of stillbirth among NRT users. It could be that NRT users comprise a group of healthier smokers who are more likely to follow preventive advice during pregnancy. Or “medical risk factors may have been less prevalent among NRT users than non-users,” the investigators explain.
