Electronic cigarettes, often marketed as a safer alternative to conventional cigarettes, may damage cells in ways that could lead to cancer, a new study has warned.
Adding to growing evidence on the possible health risks of electronic cigarettes, a team at the Veterans Affairs San Diego Healthcare System tested two products and found they damaged cells in ways that could lead to cancer.
The damage occurred even with nicotine-free versions of the products, researchers said. So far, evidence is limited on what exactly e-cigarettes contain and whether those chemicals are safe, particularly in terms of cancer.
There haven’t been many good lab studies on the effects of these products on actual human cells.
