Vaping Help Pregnant Women Quit Smoking

A new study from Queen Mary University in London suggests vaping may be more effective than nicotine patches in helping pregnant smokers quit.

Researchers also found vaping could lower the risk of having an underweight baby compared to smoking cigarettes. Low birth weight raises the chances of future health problems.

Most smoking cessation services currently recommend nicotine patches for pregnant smokers. But this study indicates vaping and patches are similarly safe during pregnancy. The key difference was a lower rate of low birthweight babies among the vaping group versus those using patches.

The scientists believe vaping simply helped more women stop smoking completely. Almost twice as many pregnant smokers quit with vaping rather than patches. Some women obtained e-cigarettes independently after being offered patches. This implies vaping was more appealing for smoking cessation.

“E-cigarettes seem better than patches for pregnant smokers to quit, leading to better outcomes,” says Professor Peter Hajek of Queen Mary University. “Current advice for smokers already includes switching to vaping. Now this recommendation can extend to pregnant smokers too.”

The specific effects of nicotine on fetuses remain unclear. The National Institute for Health and Care Excellence (NICE) believes toxins other than nicotine in cigarettes primarily cause risks. So they recommend nicotine replacement therapy like patches, gum, and sprays along with behavioral support.

A key benefit of vaping is it allows expecting mothers to select their preferred nicotine strength and flavors. This flexibility could make quitting smoking easier during pregnancy, the researchers say. More options with vaping may explain its advantages over patches and other nicotine replacements.

Smoking VS Vaping During Pregnancy

Smoking traditional cigarettes during pregnancy can harm the mother and baby. Risks include preterm delivery, stillbirth, low birth weight, and birth defects. Nicotine and carbon monoxide in cigarette smoke limit oxygen and nutrients for the developing fetus.

Quitting smoking is ideal. But nicotine addiction makes it extremely challenging. Nicotine replacement therapy including patches, gum, lozenges, and vaping can alleviate cravings and withdrawal. However, potential fetal risks from nicotine exposure remain.

The ingredients and contaminants in vaping liquids are also worrying. But vaping lacks thousands of chemicals in cigarette smoke. The reduced risks make vaping an appealing alternative for pregnant smokers struggling to quit.

While more research is required, evidence increasingly suggests vaping is less harmful than smoking during pregnancy. The study found babies born to vapers averaged nearly 1⁄3 pound heavier than babies of smokers (Low birthweight has been linked with poor health later in life). The Queen Mary University study had comparable findings.

Vaping May Improve Smoking Cessation Rates For Pregnant Women

The clinical trial by Queen Mary University of London evaluated vaping against nicotine patches. 679 pregnant smokers in England were randomly assigned patches or e-cigarettes plus counseling.

Around 37% of the vaping group stopped smoking by the end of pregnancy. Just 28% of patch users successfully quit.

15% of babies born to patch users had low birth weights compared to 6% for vaping. Low birthweight infants face higher risks of infection, developmental delays, and SIDS.

The researchers conclude pregnant smokers should receive counseling and the choice of nicotine replacements including vaping. Vaping could substantially increase their chances of totally quitting smoking during pregnancy.

Lead author Professor Peter Hajek affirms, “Healthcare providers can recommend e-cigarettes more widely as an alternative to smoking in pregnancy.”

Concerns Persist About The Unknown Long-Term Impacts Of Vaping

Despite the potential advantages over smoking, concerns remain about vaping’s long-term effects. E-cigarettes are too new to fully understand the health consequences, especially during pregnancy.

Unknown ingredients, contaminants, and varying nicotine levels in vaping liquids raise additional concerns. Manufacturers don’t have to disclose all ingredients. Standards and regulations for e-cigarette manufacturing continue to evolve.

While vaping seems less harmful than smoking, abstaining from both during pregnancy is ideal. However, vaping does appear to be an effective tool to help pregnant smokers quit.
