The flavours used in electronic cigarettes (e-cigarette), especially cinnamon and menthol, can increase the risk of cardiovascular diseases (CVD) when inhaled, says a study.
The research team investigated the effect of the e-liquids on endothelial cells that line the interior of blood vessels.
The study, published in the Journal of the American College of Cardiology, found that endothelial cells exposed to the e-liquids or to blood collected from e-cigarette users shortly after vaping, exhibit significantly increased levels of molecules implicated in DNA damage and cell death.
