A new analysis of data from the Pregnant Smokers Trial by researchers at Queen Mary University of London comes to this conclusion, that regular use of N replacement products during pregnancy is not associated with adverse pregnancy events or adverse pregnancy outcomes. The study, published today in the Journal of Addiction, conducted a secondary analysis of randomized controlled trials of e-cigarettes and N-patch pregnancy tests (PREP) through.

The purpose of this study was to, the safety of e-cigarettes (EC) and N-paving (NRT) in helping pregnant women quit smoking. The participants included 1140 pregnant smokers. Measures included N intake compared to baseline, the birth weight, other pregnancy outcomes, adverse events, maternal respiratory symptoms and relapses in first-time users. The results suggest so, that the regular use of e-cigarettes or N-patches in pregnant smokers does not appear to be associated with undesirable consequences. In particular, the use of e-cigarettes is more common than N replacement therapy, and in women, those in the third trimester of pregnancy (EOP) stopped smoking and used e-cigarettes, the cotinine level in saliva fell 45 %. Furthermore, there was no difference in birth weight between former smokers and those who smoked, who consumed N products, which suggests this, that the use of e-cigarettes and N replacement therapy later in pregnancy may have no effect on intrauterine growth. In addition, studies have shown, that taking N-products during pregnancy does not increase the risk of relapse in early users. In addition, birth analyzes were carried out- and maternal outcomes, adverse events and recurrence rates adjusted for baseline characteristics associated with the outcomes, and no significant differences were observed between participants, who consumed N products, and those, who didn't do this.

E-cigarettes are not harmful to pregnant women

In particular, the assessment of respiratory symptoms showed, that e-cigarette users experienced greater improvement in cough and phlegm than non-users, while shortness of breath and wheezing remained unchanged. The study also analyzed changes in cotinine levels in saliva and found, that regular consumption of N products was associated with specific changes in cotinine levels in dual users and smokers compared to ex-smokers and smokers. However, the study also acknowledges some limitations, knows from. B. the reliance on self-reported abstinence and the limited statistical power of some comparisons due to small sample sizes. In summary, this study shows, that the regular use of e-cigarettes or N patches does not appear to be associated with undesirable consequences in pregnant smokers.
