The electronic cigarette would be less harmful to our cells than conventional smoking.
- The effects of vaping on the genes would be less harmful than those of smoking
- The substances of electronic cigarettes would degrade the DNA of cells less
What are the effects of electronic cigarettes on our genes? Tests have been carried out in vitro, on stem cells to answer this question. In the review Mutagenesisthe scientists say they used a tool called “Toxys’ToxTracker“, which makes it possible to evaluate the effects of a chemical substance on our genes. They compared the effects of cigarette smoke to those of the liquid for electronic cigarette and the vapor which it emits. The researchers were interested in stress cells, DNA and protein degradation, and activation of the p53 gene, which is linked to cell cycle regulation and tumor suppression.
An absence of DNA degradation
According to the results of this test, the liquid and vapor of electric cigarettes do not degrade DNA compared to smoked cigarettes. “This work adds to the existing scientific literature which shows that vaping products, when they are of good quality and meet safety requirements, lead to a reduction in harm, compared to continued smoking.“, estimates Dr. Grant O’Connell, one of the authors of this research. It belongs to the laboratory Imperial Brand Scienceattached to the tobacco group of the same name.
The electronic cigarette, object of all divisions
Since its appearance, the electronic cigarette has divided the scientific community, in particular because of the lack of perspective we have. Many studies show that it is less dangerous than smoking cigarettes, while others point to the risks of vaping. “Vaping has proven effects on vessels and inflammation, as well as cell toxicityexplained Professor Daniel Thomas, former head of the cardiology department at the CHU Pitié-Salpêtrière hospital in Paris and vice-president of the Alliance against tobacco, last November at Why Doctor. For a non-smoker, the vape is therefore certainly toxic. But for smokers, exposed to thousands of toxic products on a daily basis, switching to electronic cigarettes reduces the risks to their health. In the vape, there is in particular no combustion, therefore no carbon monoxide. According to theWorld Health Organizationtobacco is responsible for more than eight million deaths worldwide every year.
