Scientists talked about the dangers of flavorings for electronic cigarette
Fragrances for electronic cigarettes, like cigarettes themselves, pose a threat to the cardiovascular system, according to the results of a study by scientists at Stanford University School of Medicine in the USA, available to RIA Novosti.”Our data show that the selected (for research) flavorings for electronic cigarettes have a negative impact on the viability and functioning of endothelial cells,” the document says.
These cells form a layer on the inner surface of the blood vessels. They participate in the process of blood coagulation, control of blood pressure, the formation of new blood vessels and perform a number of other important functions.
“We also showed that using electronic cigarettes alone can increase the plasma nicotine concentration to a level comparable to conventional cigarettes, which indicates the ability of electronic cigarettes to deliver nicotine efficiently and measurably,” the study said.

The authors of the study called for further study of the effect of electronic cigarettes on human health in connection with their increasing distribution, which, in their opinion, should help formulate approaches to regulation in this area.For work, serum samples were taken from five healthy non-smokers, five people who smoke cigarettes, two people who use only electronic cigarettes, and two people who smoke both regular and electronic cigarettes. They were exposed to solutions containing six commercially available flavors. The results for different flavors were different.
For example, mixtures with the smell of cinnamon and tobacco with menthol had the greatest cytotoxic effect on the cells.
Mixtures with the aroma of sweet tobacco with caramel and vanilla, a fruit mixture and two others had a moderate effect.The authors of the study concluded that flavorings can contribute to cell death, oxidative stress, that is, damage to endothelial cells. This, in turn, affects their functioning, and taking into account their role in the body can be a risk factor for cardiovascular diseases.
It was previously reported that Swiss researchers found traces of the toxic substance isocyanate in electronic cigarettes IQOS, which could harm the lungs. Philip Morris, which produces cigarettes, acknowledged the problem, but emphasized that the company itself conducted cigarette research in real conditions and is confident that isocyanate does not enter the lungs when smoking.
