Long-term vaping does not affect the lungs

The study was conducted by Professor Polosa, Director of the Institute of Internal Medicine and the Smoking Cessation Center at the University of Catania, and won the INNCO Global Award in June.

Preliminary evidence that long-term vaping does not cause health problems
Professor Riccardo Polosa's team followed a group of young people who had never smoked but regularly used e-cigarettes. The volunteers were monitored and tested for three and a half years and their results were compared with a group of people who did not use these two types of products.

"On HRCT, we did not observe any deterioration in lung function, signs of lung inflammation, or lesions compared to a group of non-smokers who did not use e-cigarettes," the researchers said. Even the most frequent users showed no signs of lung damage or inflammation, and there were no changes in blood pressure or heart rate, the researchers noted.

Professor Polosa's explanation of arteriosclerosis
These findings provide doctors with answers to the question of hardening of the arteries. A study presented at the European Respiratory Society meeting held in Milan, Italy in September 2017, showed that vaping can increase body mass index and cause temporary hardening of the arteries.

In response to the above question, Professor Peter Hajeck, director of tobacco research at Queen Mary University of London, pointed out that there are other activities that have the same effect on the body without any harm. "This is the usual stimulant effect of nicotine and it is completely harmless. Drinking a cup of coffee has the same effect."

Larger studies are needed
Professor Polosa's study, published in the journal Science, found that although the study was small, "the results provide preliminary evidence that long-term use of e-cigarettes does not have adverse health effects." However, the team also said that more in-depth, larger-scale studies are needed.
