While e-cigarettes have been in the spotlight for their popularity among kids and an ongoing outbreak of lung injury due to illegal products, many have also looked to them as a potentially less harmful alternative to smoking. CNN reports on new research published in the Journal of the American College of Cardiology suggests that adult smokers’ heart health might benefit from switching to e-cigarettes. The study of 114 people found early measures of improved blood vessel health, such as “Vascular stiffness,” within a month of switching from combustible cigarettes to their electronic counterparts. The results did not depend on whether the e-cigarette contained nicotine or not. The authors hypothesized that “Early improvement appears to be unrelated to the abstinence from nicotine, but rather from other toxic material produced by combustion” in conventional cigarettes.
