The vaper at risk, even in small doses
To prove it, the team of Professor Emily Bates, the main author of the study, exposed pregnant mice to a dose proportional to what a future mother vaping daily can absorb. In detail, “fetuses that were exposed to vaping ended up having smaller and shorter bones during their development.” In addition, nicotine “has an impact on activated genes in the lungs of the fetus”.
And you don’t need a lot of nicotine to impact fetal development. “Even low levels of e-cigarette vapor during pregnancy inhibit growth,” the researchers attest. How to explain this risk? “Nicotine passes through the placenta into the fetal circulation where it can accumulate to levels higher than in maternal plasma. This disrupts the development of several organs and systems. »
To best protect pregnant women and unborn children, the effects of electronic cigarettes containing nicotine must be taken into account. A public health priority as “the popularity of vaping among young people, the addictive nature of nicotine and the lack of perceived risk suggest that vaping during pregnancy is likely to increase over time,” concludes Professor Bates.
