E‐cigarettes and pregnancy. Is a closer look appropriate?

Cigarette smoking is perhaps the single most important avoidable causes of adverse pregnancy outcomes and is a particularly important problem for women at social disadvantage, such as Indigenous Australians. Fortunately, pregnancy motivates many women to stop smoking with about 40% of smokers quitting in the first trimester. However, women who quit in early pregnancy are likely to be those with the best prognosis, leaving the more ‘dedicated’ smokers as the subjects of quit programs. Quit programs are generally ineffective for women who continue to smoke past the first trimester with the worst results for women at greatest risk: those who are heavy smokers; have partners who also smoke; and have limited access to antenatal care. Trials of nicotine replacement therapy (NRT) in pregnancy have also been disappointing as the majority of pregnant women who commence NRT therapy in clinical trials stop using it before completion of the trial. Vaping’ – the use of e-cigarettes – is now an important trend, and a recent trial found that e-cigarettes are at least as effective as other forms of NRT in smokers, but seem to have higher rates of compliance presumably due to their similarity to the act of smoking. In the light of these findings, is it time to look more closely at vaping in pregnancy?
