E-cigarettes aren’t considered as risky as regular cigarettes, but researchers have found a clue that their flavorings may be bad for the heart.
In one study, vaping and some flavorings, even without nicotine, triggered blood vessel dysfunction that can increase the risk of heart disease, researchers reported in the Journal of the American College of Cardiology. Cinnamon and menthol seemed the most toxic. But overall, cells showed signs of damage and were inflamed, less able to form new blood vessels or heal wounds.
Small laboratory studies like this one can’t prove vaping really does harm, cautioned Dr. Jane Freedman of the University of Massachusetts, who wasn’t involved in the research. But she said the work should spark additional safety testing.
