The study showing that the nicotine free e-cigarettes; can damage blood vessels. Smoking e-cigarettes, also called vaping; has been marketing as a safe alternative to the tobacco cigarettes and is rising in the popularity among non-smoking adolescents. However, a single e-cigarette can be harmful to the body’s blood vessels; even when the vapor is entirely nicotine free according to a new study by researchers.
But the short-term impacts of vaping, the researchers performed MRI exams on 31 healthy, non-smoking adults before and after vaping a nicotine free e-cigarette. Comparing the pre- and post-MRI data, the single episode of vaping resulted in reduced blood flow and impaired endothelial function in the large (femoral) artery that supplies blood to the thigh and leg.
Alternative to tobacco cigarettes
The endothelium, which lines the inside surface of blood vessels, is essential to proper blood circulation. Once the endothelium is damaged, arteries thicken and blood flow to the heart and the brain can be cut off, resulting in heart attack or stroke. While e-cigarette liquid may be relatively harmless, the vaporization process can transform the molecules primarily propylene glycol and glycerol into toxic substances.
Beyond the harmful effects of nicotine, we’ve shown that vaping has a sudden, immediate effect on the body’s vascular function, and could potentially lead to long-term harmful consequences. E-cigarettes are battery-operating devices; that convert liquid into aerosol, which is inhaling into the user’s lungs. Typically, the liquid contains addictive nicotine, as well as flavors. More than 10 million adults in the United States use e-cigarettes, and vaping has become especially popular among teenagers.
Dangers of smoking
While there appears to be some consensus that vaping may be less harmful to health than tobacco cigarette smoking, the dangers of e-cigarettes remain unclear. In this study, the researchers examined the impact of an e-cigarette that contained propylene glycol; and glycerol with tobacco flavoring, but no nicotine, which study participants took 16, three-second puffs from.
To evaluate vascular reactivity; the group constricting the vessels of the thigh with a cuff; and then measuring how quickly the blood flowing after its release. Using a multi-parametric MRI procedure; researchers scanning the femoral artery; and vein in the leg before and after each vaping episode to see how vascular function changing. Clearly if there is an effect after a single use of an e-cigarette; then you can imagine what kind of permanent damage could be caused after vaping regularly over years.
