While there is a growing body of evidence to support the theory that e-cigarettes are less harmful than the cigarettes they look to replace, could e-cigs themselves actually have a negative impact on the human heart? According to one new study, there’s a chance that that could very well be the case for nicotine infused e-cigarettes, but only those that dispense nicotine. The findings of this study, which was led by UCLA professor of medicine Dr. Holly Middlekauff, could pave the way for more research into the effects of nicotine on the heart.
In the study, which was published in the Journal of the American Heart Associated, Middlekauff and her fellow research scientists examined 33 healthy individuals that neither smoked nor vaped, at least not currently. The study’s participants were then asked to puff on either a placebo containing no active ingredients, an electronic cigarette filled with a nicotine solution, or an e-cig containing no nicotine. And what did they find? They found that the e-cigs containing nicotine caused the user’s adrenaline levels to rise, leading the researchers to believe that there could be a correlation between nicotine and heart health – and not a good one at that.
Still, even with this in mind, Middlekauff can’t help but suggest based on the results of her prior research that smokers give up smoking for vaping, adopting e-cigarettes in place of traditional cigarettes. But for those who neither smoke nor vape, it is perhaps best to keep it that way, at least that’s what her latest research seems to suggest. Or in her own words, Middlekauff, who was quoted by Time, said that for non-smokers, she “would strongly advise that you not start using e-cigarettes, because they are not harmless.”
“The way I think about it is that if you currently smoke tobacco cigarettes, switching to e-cigs may be a better choice, at least from the data we have (…) But if you don’t smoke at all, I would strongly advise that you not start using e-cigarettes, because they are not harmless.”
