Over the past decade, e-cigarette use has skyrocketed, with it being the most commonly consumed tobacco product among U.S. youth. The move toward e-cigarette use was due in large part to the fact that e-cigarettes were believed to be a safe alternative to smoking traditional cigarettes. Indeed, according to a report by the U.S. Surgeon General, a significant portion of e-cigarette users classify themselves as “former smokers” who picked up the habit again once e-cigarettes became prevalent.
According to a recent study, however, e-cigarettes may pose a significant risk to users’ health. The study was conducted by a group of researchers at the New York University School of Medicine. The researchers exposed lab mice to a vapor that contained nicotine, similar in both content and amount to the vapor that is released by e-cigarettes.
At the conclusion of the study, researchers discovered that the DNA contained in the lungs, hearts, and bladders of the exposed lab mice suffered DNA damage. What’s more, the normal DNA repair processes were hindered. After conducting further analysis on human lung and bladder cells, the researchers confirmed that the vapor had the same halting effect on the DNA repair processes.
