On November 11, the political activist group The American Heart Association (AHA) issued a press release claiming that vaping is just as bad for the heart as smoking. By the end of the week, a group of highly regarded cardiologists debunked those asserts by publishing a study entitled Cardiovascular effects of switching from tobacco cigarettes to electronic cigarettes. Unlike the initial AHA press announcement, the medical professional’s underlying peer-reviewed research is published in the Journal of the American College of Cardiology (JACC) for the world to see.
The JACC vaping study involving 114 participants determined that adult smokers who switch to electronic cigarettes experience vast improvements in “vascular stiffness,” or improved health of the cardiovascular blood vessels, within 30-days of making the switch. Other findings suggest that female smokers-turned-vapers tend to exhibit greater levels of vascular improvement because “female smokers face more health risks than male smokers do.”
Furthermore, the study found that to achieve the maximum health benefits of vaping, the smoker’s transition to electronic cigarettes must be as complete as possible. There are also “no differences” in improved heart health effects regardless of whether the vaper is using nicotine-based or zero-nicotine products.
“Within 1 month of switching from TC [Tobacco Cigarettes] to EC [Electronic Cigarettes], there was a significant improvement in endothelial function (linear trend β = 0.73%; 95% confidence interval [CI]: 0.41 to 1.05; p < 0.0001; TC vs. EC combined: 1.49%; 95% CI: 0.93 to 2.04; p < 0.0001) and vascular stiffness (−0.529 m/s; 95% CI: −0.946 to −0.112; p = 0.014). Females benefited from switching more than males did in every between-group comparison. Those who complied best with EC switch demonstrated the largest improvement. There was no difference in vascular effects between EC with and without nicotine within the study time frame.”
This last line is particularly noteworthy because it proves that the nicotine found in both combustible tobacco products and electronic cigarettes is not the overwhelmingly important public health issue. Where e-cigs and conventional cigarettes differ is that the latter involves the burning of tobacco leaves, which results in smokers ingesting potentially deadly and highly carcinogenic levels of tar. It is this tar that clogs the cardiovascular blood vessels and arteries, not the nicotine. Additional scientific research debunking these “vaping is bad for the heart” myths was published in 2015 by the United Kingdom’s Public Health England further determined that vaping is 95 percent less harmful than smoking.
