Vaping puts chemicals into your mouth that modify DNA and increase cancer risk, new research shows.
Recently, a study showed how the electronic cigarette could weaken the lungs. One thing is certain, as scientists examine the consequences of vaping on health, we are learning that it is not without risk, even if favoring the e-cigarette over the traditional cigarette remains all that is needed. even preferable. It is better to do without both, however.
A team of researchers from Minnesota (United States) has indeed discovered that the vapor device installed in electronic cigarettes introduced three chemicals into the mouth that damage DNA. They presented their work at the 256th National Meeting & Exposition of theAmerican Chemical Society in Boston, this Monday, August 20.
Is the vapor toxic?
All electronic cigarettes are based on the same principle. The user presses a button and a trigger. At this time, a small amount of liquid is drawn into a chamber. Then, a heating battery atomizes this liquid, which releases vapor. The latter is then sucked into the lungs of the vapoteur. This process does not have the same toxic effects as smoking, such as the combustion effect for example. But some liquids contain solvents, preservatives or even chemicals. aromas who can be dangerous. Studies have already demonstrated this.
Three chemicals in the mouth
But until now, previous studies of chemicals inhaled by e-cigarette consumers have not been conducted directly in humans. Scientists in Minnesota therefore examined the chemicals present in the mouths of five e-cigarette users after fifteen minutes of vaping.
Five healthy people who do not vape served as witnesses. Researchers have detected the presence of three chemicals in the mouths of e-cigarette users: acrolein, methylglyoxal and formaldehyde.
Cancer risks
These three substances can create what is called a DNA adduct. If left unchecked, this DNA adduct can alter gene expression and lead to a cancer mutation. In addition, all five study participants, who vaped, had increased levels of acrolein-linked DNA additives.
The study’s authors recommend further research of this type on more witnesses. In any case, the scientists insist: even if the e-cigarette vapor has harmful consequences on health, they have nothing to do with tobacco. “Comparing electronic cigarettes and tobacco cigarettes is really comparing apples to oranges. The exposures are completely different,” says Silvia Balbo, lead author of the study.
