Study : Vaping daily would not cause lung damage

Introduction

A recent study comparing potential lung lesions indicates that vapers do not suffer any lung lesions, compared to non-vapers. The study was conducted with a cohort of non-smokers who vaped daily for several years.

Presentation of the study

This study was conducted by Professor Polosa, Director of the Institute of Internal Medicine and Anti Smoking Center at the University of Catania, who received an award last June from the International Network of Nicotine Consumer Organisation.

Professor Riccardo Polosa and his team followed a small sample of young adults who had never smoked but used e-cigarettes daily. Participants were followed for about 3 and a half years, and their results were compared with a control group of non-smokers who had never used an e-cigarette.

"We found no decrements in spirometric indices, development of respiratory symptoms, changes in markers of lung inflammation in exhaled air, when compared with non-smokers non-vapers" reported the authors of the study. They add that even the heaviest users failed to exhibit any evidence of damage or inflammation in the lungs and no changes in blood pressure or heart rate.

Polosa’s study addresses the concerns about arterial stiffness

These findings address the concerns raised by many health professionals who linked e-cigarettes to arterial stiffness. In fact, a study presented to the European Respiratory Society (ERS) International Congres in September 2017 had pointed out the fact that vaping momentarily increases vital signs and arterial stiffness.

Replying on the foregoing, Professor Peter Hajek, director of the Tobacco Dependence Research Unit at Queen May University in London (QMUL) has pointed out that other things have the same effect on the body and are considered irrelevant in terms of health risks. "The stimulating effect of nicotine is well known and has little impact on the health. Drinking coffee has the same effect, it's just longer lasting (just like watching a dramatic football game)."

Conclusion

Polosa's study, which was published in Scientific Reports, finds that while the sample size was small, "the results of this study may provide some preliminary evidence that long-term use of an electronic cigarette is unlikely to raise significant health concerns in relatively young users." However, according to researchers, further studies with larger samples are needed.
