E-Cigarettes loaded with nicotine-based liquid may be as Harmful as Smoking, says Research

Modern e-cigarettes, viewed as a less toxic alternative for people looking to break their habit of smoking tobacco cigarettes, have steadily risen in popularity since they first appeared on the commercial market in 2004

New York, June 12, 2017: Electronic cigarettes loaded with nicotine-based liquid are potentially as harmful as tobacco cigarettes when it comes to cancer-causing DNA damage, new research has found.

Electronic cigarettes or e-cigarettes are battery-powered devices that heat up liquid and turn it into an aerosol vapour that can be inhaled. Using e-cigarettes is also called ‘vaping’.

“From the results of our study, we can conclude that e-cigarettes have as much potential to cause DNA damage as unfiltered regular cigarettes,” said the lead author of the study, Karteek Kadimisetty, from University of Connecticut.

Cellular mutations caused by DNA damage can lead to cancer.

Modern e-cigarettes, viewed as a less toxic alternative for people looking to break their habit of smoking tobacco cigarettes, have steadily risen in popularity since they first appeared on the commercial market in 2004.

The scientists decided to look into whether the chemicals in e-cigarettes could cause damage to human DNA while testing a new electro-optical screening device they developed in their lab.

The small 3-D printed device is believed to be the first of its kind capable of quickly detecting DNA damage, or genotoxicity, in environmental samples in the field, the researchers said.

They gathered samples through an artificial inhalation technique at 20, 60 and 100 puffs of an e-cigarette. The potential DNA damage from e-cigarettes was found to increase with the number of puffs.

Vapour from non-nicotine e-cigarettes caused as much DNA damage as filtered cigarettes, possibly due to the many chemical additives present in e-cigarette vapours, showed the findings published in the journal ACS Sensors.

“Some people use e-cigarettes heavily because they think there is no harm. We wanted to see exactly what might be happening to DNA (as a result of e-cigarette usage),” said Kadimisetty. (IANS)

Avoid Smoking During Pregnancy To Prevent Premature Births

The negative health impacts of cigarette smoking during pregnancy, including low birth weight, delayed intrauterine development, pre-term birth, infant mortality, and long-term developmental delays, are well known.

Expecting mothers, take note. As smoking during pregnancy is linked with negative health outcomes, a team of researchers has found that smoking cessation during pregnancy may reduce the risk of pre-term birth.

The findings, published in the JAMA Network Open journal, showed that the probability of pre-term birth decreased with earlier smoking cessation in pregnancy — up to a 20 per cent relative decrease if cessation occurred at the beginning of pregnancy.

“Of concern, though, given the substantial benefits of smoking cessation during pregnancy is that the proportion of pre-pregnancy smokers who quit smoking during pregnancy has remained essentially stagnant since 2011,” said lead author Samir Soneji from The Dartmouth Institute for Health Policy and Clinical Practice in the US.

For the study, the researchers conducted a cross-sectional study of more than 25 million pregnant women who gave birth to live neonates during a six-year period — measuring their smoking frequency three months prior to pregnancy and for each trimester during pregnancy.

The negative health impacts of cigarette smoking during pregnancy, including low birth weight, delayed intrauterine development, pre-term birth, infant mortality, and long-term developmental delays, are well known.

But the good news is that the proportion of women who start their pregnancy as smokers has been declining in recent years, the researchers said.

However, the study also found that only about 25 per cent of women who smoked prior to pregnancy were able to quit throughout their pregnancy, and approximately 50 per cent of women who smoked during their pregnancy did so with high frequency (more than 10 cigarettes per day).

The researcher plans to look at quit rates and smoking intensity and their impact on the risk of infant mortality.

“Thankfully most premature babies end up doing well,” he said.

“But premature birth is strongly linked to infant mortality. If we determine quitting, and quitting early, reduces the risk of infant mortality, then that may speak to mothers even more saliently about the importance of smoking cessation,” he added. (IANS)
