Pregnant women may be unaware of possible e-cigarette risks

In a small U.S. study, nearly half of all pregnant women surveyed did not think electronic cigarettes contain nicotine or know that the devices can be addictive.

Almost half of the group of 316 pregnant women also believed e-cigarettes were less harmful to their fetuses than traditional cigarettes, when in fact the safety of using e-cigarettes while pregnant has not been determined, researchers say.

Victoria Coleman-Cowger, one of the study’s authors, said in an email that while e-cigarette use has increased considerably over the past few years, many people, including pregnant women, are not well informed about them.
