Electronic cigarette: carcinogens stored in the lungs during vape

Is the e-cigarette more or less toxic than the traditional cigarette? Since commercialization on a large scale fifteen years ago, scientific studies have followed each other and are contradictory. According to one of the most recent, published by American researchers on August 7 in the scientific journal Toxics, the smoker would absorb many toxic chemicals, such as formaldehyde in vapors, which can increase the risk of cancer.

Vera Samburova, from the Nevada Research Institute, and her team have been working for several years on the risks of e-cigarettes. In this new study, researchers analyzed the breathing of twelve consumers of e-cigarettes before they broke. For more realism, most participants used their own devices and liquids and vods as they had done in the comfort of their home.

Scientists then subtracted the concentration of chemicals found in the smokers from the smokers from the rate found in the vapors coming from the vessel, with the difference being recorded in the lungs of the vapers. And the result is the scariest: "We discovered that the average concentration of aldehydes after a vapor session was ten times higher than before," says Vera Samburova.

New study must be carried out on a larger group of participants

"Later we saw that the concentration of chemicals such as formaldehyde in post-vaping breathing was hundreds of times lower than what we found in the vapors of electronic cigarettes, meaning that a significant percentage of them remained in the smoker's airways," she continues. . "So far, the only research on the amount of aldehydes that has been blown in during smoking is done by consumers of conventional cigarettes," she says.

"Our study shows the potential risk associated with the aldehydes generated by the electronic cigarette," explains Vera Samburova, before deciding: "In the future, the exposure to aldehydes caused by the e-cigarette must be studied on a larger scale. ", she concludes.

Risk of heart attack and modification of DNA

Whereas since February 2016 the High Council for Public Health (HCSP) considers the electronic cigarette as an aid to stop or reduce smoking by smokers, many studies regularly prove the harmfulness of this technology because of the products in its products. liquids. According to another US survey published in May, vape daily doublewould the chance of a heart attack. A few months later, other scientists, including Americans, have now discovered that the vapor device installed in electronic cigarettes put three chemicals into the mouth that damaged the DNA.

Given the number of conflicting investigations published on the subject on a regular basis, the American Academy of Sciences published a 600-page report in January last year in which 800 studies on this topic were compared. The results of the latter are classified based on their severity.
