Amid ongoing debates, a rigorous Scottish study demonstrates that switching from traditional cigarettes to e-cigarettes enhances cardiovascular health—with benefits emerging in just one month.
"Over one month, we observed an average 1.5 percentage point improvement in cardiovascular function among smokers who switched to e-cigarettes," states Jacob George, a researcher at the University of Dundee in Scotland, in a November 15, 2019, press release. "Each percentage point gain correlates to a 13% reduced risk of major cardiovascular events, like heart attacks."
Published in the Journal of the American College of Cardiology, this study tracked 114 smokers over one month, divided into three groups assessed for cardiovascular function before and after.
Group one continued smoking regular cigarettes. Group two used nicotine-containing e-cigarette liquids. Group three vaped nicotine-free liquids. Results confirmed vaping improves endothelial function—the blood vessels' ability to retain blood while facilitating nutrient exchange.
In the U.S., a recent outbreak of mysterious lung illnesses—2,000 cases and around 40 deaths—damaged e-cigarettes' reputation. Investigators linked it to counterfeit liquids containing THC, vitamin E acetate, and pesticide residues, a issue specific to unregulated products.
Study leaders stress that e-cigarettes are less harmful than smoking for cardiovascular health, but far from risk-free. This research highlights relative benefits only; vaping isn't advisable for non-smokers or youth.
