The risks of e-cigarettes
People who use e-cigarettes daily may be significantly increasing their risk of a heart attack, reports ScienceDaily.com. Scientists examined data from two national surveys with a combined 69,000 respondents. They found that compared with people who never had e-cigarettes, daily users were twice as likely to have a heart attack. That’s still an improvement on conventional cigarettes, which almost triple the risk of an attack. But more than two thirds of the e-cigarette users were also conventional smokers—and their risk was five times higher than that of nonsmokers. “Vaping” delivers a powerful dose of nicotine, which has a proven negative impact on heart health. The study did offer some good news for e-cigarette users: The risk of a heart attack starts to drop as soon as they stop, as it does for conventional cigarettes.
