People who puff electronic cigarettes every day have twice the risk of heart attack, and the odds increase almost fivefold for those who use them along with traditional cigarettes, a new study suggests.
“Using both products at the same time is worse than using either one separately,” said senior study author Stanton Glantz. He’s director of the Center for Tobacco Control Research and Education at the University of California, San Francisco.
Most adults who vape continue to smoke tobacco cigarettes, he added. About 66 percent of the nearly 2,300 current e-cigarette users in the study also smoked tobacco cigarettes.
