Study participants smoked but had never vaped before. Both smoking & vaping delayed blood vessels from dilating back to normal (as does caffeine.) It's long been understood that people with PREEXISTING heart conditions should avoid nicotine/caffeine.
Researchers did not appear to take into consideration that carbon monoxide, which also has been linked to atherosclerosis, is present in cigarette smoke but NOT present in e-cigarette vapor. Eliminating carbon monoxide exposure means less risk to the heart. That means SAFER.
Furthermore, in 2013 the FDA stopped requiring nicotine gum labels to advise only 12 weeks of use, because studies showed "adverse effects...were described as MINOR AND TRANSIENT, and there was NO CORRELATION between long-term gum use and cardiovascular events." So, nicotine gum doesn’t appear to raise the risk of heart attack, but somehow nicotine vapes do? Hmmm...something is fishy here.
