Vaping During Pregnancy: What the Research Says

As vaping gains traction as a smoking cessation tool, its safety for expecting mothers remains unclear. A recent study suggested vaping could enable quitting cigarettes in pregnancy without harming the baby. But experts urge pregnant women to exercise caution amid limited data.

The Controversial New Study

A 2024 study from Queen Mary University of London analyzed over 1,100 pregnant smokers using nicotine replacements (NRTs) like patches or vapes to quit smoking.

Researchers found no detectable risks to babies' birth weights for vaping mothers compared to non-smokers. Lead author Professor Peter Hajek concluded "e-cigarettes helped pregnant smokers quit without posing risks.”

But other experts critique the study's limits, including small sample sizes and lack of long-term tracking. The American College of Obstetricians and Gynecologists stresses “there are no safe tobacco products” while pregnant.

Expert Guidance: Avoid Vaping If Possible

UK health bodies acknowledge vaping’s harm reduction potential for quitting cigarettes. Yet they still urge caution for pregnant vapers given unknowns around long-term effects.

Prof Linda Bauld, a public health expert from Edinburgh University, commented: “Ideally pregnant women using nicotine vaping products to stop smoking should be supported to come off them eventually.”

And Dr. Pat O’Brien said “vaping does expose babies to nicotine which may have an effect on development.” He advised prescribing nicotine patches over vaping if NRT is required, with goal of weaning off nicotine entirely by week 12.

So while vaping could enable some mothers to quit smoking, ceasing all nicotine intake remains ideal. Patients should consult their doctor about use of vaping or NRTs during pregnancy.

Key Takeaways for Prospective Parents

Amid scarce and conflicting research, definitive guidance remains lacking. But a few key suggestions emerge:

- Quitting smoking and nicotine entirely is safest

- Discuss NRT use with your doctor if struggling to quit cigarettes

- Opt for patches over vaping if NRT is recommended

- Monitor childhood development for any effects

Stay apprised of new studies, but know unknowns persist around long-term impacts. Ultimately to minimize uncertainty, avoid smoking and vaping while trying to conceive and during pregnancy when feasible.
