The Miami Herald reports, “The number of U.S. high school students who reported being e-cigarette users increased a whopping 78 percent from 2017 to 2018, to 3.5 million,” according to CDC data. Researchers say the increase is the result of “the appealing design of e-cigarette products, the high nicotine content, and the enticing flavor options, namely fruit and candy flavors.” Meanwhile, investigators express concern that e-cigarette use may impact heart health; one study found it “increases inflammation in endothelial cells,” while another “suggests that people who smoke e-cigarettes are more likely to suffer from heart disease and stroke than non-smokers.”
