The sweet flavorings in e-cigarettes may cause damage to the cells in the blood vessels and the heart.
Researchers at the Boston University School of Medicine took a look at what happens when cells, which line the arteries, veins and inside the heart, are exposed to popular e-cigarette flavorings.
At high concentrations, all flavorings caused damage.
However, they found that vanilla, mint, cinnamon, and clove appeared to impair the production of nitric oxide -- which is known to cause heart attacks and strokes.
