Is it safe to vape while breastfeeding?

April 27, 2020

Bethesda, MD - Findings from a new animal study suggest that maternal nicotine exposure during breastfeeding could be linked to problems with skull and face development. Although widespread research has focused on the effects of cigarettes, little work has examined nicotine alone.

"Unlike many other studies, we isolated the common constituent of cigarettes, vaping technologies and many nicotine replacement therapies to specifically understand how nicotine by itself might alter development," said research team leader James Cray, PhD, associate professor of anatomy at The Ohio State University. "Our findings suggest that mothers who vape while breastfeeding are likely exposing their infants to nicotine and that this can disturb growth much like cigarette exposure."

Amr Mohi, BDS, a teaching assistant and graduate student in Cray's lab, was scheduled to present this research at the American Association for Anatomy annual meeting in San Diego this month. Though the meeting, to be held in conjunction with the 2020 Experimental Biology conference, was canceled in response to the COVID-19 outbreak, the research team's abstract was published in this month's issue of The FASEB Journal.

Maternal exposure to nicotine has been linked to increased craniofacial abnormalities such as craniosynostosis, a birth defect in which the bones in a baby's skull fuse too early. To better understand the timing involved in this exposure, the researchers used an imaging method known as microCT to measure skull and face bones in mouse offspring after maternal nicotine exposure during pregnancy or lactation.

The researchers found that exposure during lactation alone--comparable to the time a mother would breastfeed her infant--was associated with abnormalities in craniofacial development.

"Our findings suggest that nicotine alone can alter craniofacial development and show that nicotine cannot be viewed as a relatively safe chemical that only acts on addiction," said Cray.

The researchers plan to build on these findings by looking more closely at nicotine exposures from vaping. In one study, they are using cell models to better understand how nicotine and carrier components used for vaping may alter cellular processes.

What If?
There's plenty of speculation about what Donald Trump might do in the wake of the election. Would he dispute the results if he loses? Would he simply refuse to leave office, or even try to use the military to maintain control? Last summer, Rosa Brooks got together a team of experts and political operatives from both sides of the aisle to ask a slightly different question. Rather than arguing about whether he'd do those things, they dug into what exactly would happen if he did. Part war game part choose your own adventure, Rosa's Transition Integrity Project doesn't give us any predictions, and it isn't a referendum on Trump. Instead, it's a deeply illuminating stress test on our laws, our institutions, and on the commitment to democracy written into the constitution. This episode was reported by Bethel Habte, with help from Tracie Hunte, and produced by Bethel Habte. Jeremy Bloom provided original music.
