Getting started with vaping without stopping smoking does not necessarily have a health benefit. This is what a new study led by American researchers reveals, which specifies that combining vaping and smoking would not reduce the risk of developing cardiovascular diseases.
Researchers from the Boston University School of Public Health used data from 7,130 participants in Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health (PATH) study to learn more about the effects of vaping on cardiovascular health; little data has been published on the subject.
Faced with the impossibility of measuring the effects of such a short-term exposure, the scientists more specifically looked for potential cardiovascular inflammation and oxidative stress, two biomarkers known as predictors of certain cardiovascular events such as heart failure and seizures. cardiac.
The study first found that participants who had taken up vaping exclusively were no more likely to suffer from cardiovascular inflammation or oxidative stress than those who did not consume traditional cigarettes or electronic cigarettes. However, they also found that participants who smoked and vaped were just as likely to suffer from it as those who smoked tobacco exclusively.
This finding is important, since the researchers specify that nearly 68% of people who vape in the United States also smoke traditional cigarettes. “The dual use of cigarettes and e-cigarettes appears to be as harmful to cardiovascular health as exclusive smoking. (…) If e-cigarettes are used to quit smoking, cigarettes should be completely replaced and a plan to get rid of all tobacco products should be advised, ”emphasizes Dr Andrew Stokes, lead author of the study.
The researchers say, however, that they did not expect to find that participants who smoked e-cigarettes exclusively would achieve similar results to non-smokers, even though this exclusive use was found to be rare in the sample.
Which now requires additional research.
They also evoke the fact that data exist on the presence of “harmful or potentially harmful constituents” in the aerosols of electronic cigarettes, although at lower concentrations compared to traditional cigarettes, recalling that “the use of these products are not without risk ”.
