NPR reports a study by the American Heart Association of 400,000 people found that “e-cigarette users had a 71 percent higher risk of stroke, 59 percent higher risk of heart attack, and 40 percent higher risk of heart disease.” The study is to be presented February 6 at the American Stroke Association’s International Stroke Conference in Honolulu. Stanton Glantz, a tobacco and e-cigarette researcher at University of California, San Francisco, was not involved in the research, speculated that e-cigarettes could exacerbate a condition of pre-existing arterial buildup, triggering “a bunch of inflammatory processes, the release of oxidizing agents and things which then interfere with normal functioning of the blood and blood vessels.”

Study author and University of Kansas in Wichita assistant professor Dr. Paul Ndunda told Newsweek the study is the first linking e-cigarette use and stroke and also one of the largest showing an association between heart disease and e-cigarette use. Ndunda said, “Those that vape as a smoking cessation aid need to have a discussion with their doctors. There may be other effective methods suitable for them.”
