USA – Nbcnews.com writes that new research indicates that vaping might be more hazardous to health than smoking. The health risks associated with smoking cigarettes are well-known and rarely disputed. E-cigarettes entered the market ostensibly as a safer alternative to traditional cigarettes. Manufacturers of e-cigarettes claimed their products could help smokers quit and provided a far safer option for those addicted to cigarettes.
A study carried out at the Boston University School of Medicine found that e-cigarette smokers have higher levels of LDL, which is the unhealthy type of cholesterol, than people who do not smoke or vape. Both smokers and participants who vape had lower levels of HDL, which is the healthy type of cholesterol, than did participants in the study who did not use either product.
A second study looked at the impact of vaping and smoking on blood flow during exercise and at rest. The study observed individuals who did not use any nicotine products, smokers, and vapers. As with previous studies, participants who smoke had reduced blood flow during exercise as compared to those who were in the non-smoker group. After exercise, the smokers’ blood flows returned to normal. When observing e-cigarette users, the study found that these participants experienced reduced blood flow both while exercising and while at rest. This study indicated that vaping might have an even more harmful impact on the heart’s ability to pump blood than smoking does.
A previous study indicated that vaping restricts blood flow, even without nicotine. The study showed that blood vessel function is impaired when vaping flavors or sweeteners and that the impairment remains for around one hour after the person vapes.
The impact of vaping on a person’s lungs is already well-known. The Centers for Disease Control and Prevention is following the growing epidemic of “e-cigarette or vaping-related lung injuries” or EVALI. This condition is already responsible for 39 confirmed deaths and more than 2,000 illnesses in the United States this year.
