According to various estimates, from half to four percent of Russians smoke electronic cigarettes, and their popularity is only growing. The main reason is confidence in the relative safety of vaping. Smokers hoping thus to get rid of bad habits. However, the world health organization (who) warns against the overuse of electronic cigarettes and the Ministry of industry and trade has developed the bill, offering to equate them to the usual: to restrict the sale and ban Smoking in public places.

Rats-smokers

In 2016 in one of the laboratories of the Crimean Federal University named after V. I. Vernadsky, a group of biologists made two dozen rats, «Smoking» electronic cigarettes. The animals were placed in the seed chamber where the aerosol was injected beznikotinovye liquid commonly used in vapuh. Rodents received a daily dose of the smoker in terms of your weight — 0.005 milligram of liquid. One third of the rats regularly inhaled aerosol during the week, a third 30 days, the remaining two months.

The researchers then compared the lungs of rats smokers and animals from the control group. It turned out, the longer the rodents breathed cigarette aerosol, the worse it looked for their respiratory system. Biologists have documented atelectasis (when a lobe of the lung is actually blown away), swelling and thinning mezhalveolyarnyh partitions, significant changes in the bronchi.

According to scientists, the internal organs of rodents so badly damaged, likely from propylene glycol and glycerin contained in almost all liquids — both nicotinic and beznikotinovye, who runs the electronic cigarette. These substances after prolonged inhalation cause irritation of the respiratory tract, eyes, adversely affect the Central nervous system.

In addition, aerosol liquids for wapow contain heavy metals — tin, Nickel, copper, lead, chromium, in concentrations sometimes a hundred times more than conventional cigarettes. As noted by researchers from the University of California, riverside (USA), nanoparticles of Nickel and chromium fall within the aerosol from the heating element. Penetrating into the alveoli of the lungs, they have a local toxic effect, and then spread arterial blood throughout the body.

When Smoking poisoned not only the fans of wapow, but also the surrounding. Scientists from the University of California, Berkeley, measuring the levels of hazardous substances in the bar, where is allowed to smoke electronic cigarettes, found that the concentration of toxins that is several times greater than safe performance. Especially many of the formaldehyde — substances used in the furniture industry, in the manufacture of plastics and paint products.

But even with these frightening values of the levels of this dangerous toxin causing leukemia, brain cancer and serious damage to the ovaries, in the ambient air is several times lower than in the vapor inhaled by smokers. According to the staff of the University of Nevada and desert research Institute, this means that a large number of toxic substances deposited in the smoker.

Some scientists believe that e-cigarettes are not as dangerous as commonly believed, but is rather a marginal point of view not supported in the scientific community. There are studies showing that the incidence of cancer among vapers lower than among regular smokers. And according to the report of the Ministry of UK health, electronic cigarette — the most effective way to quit Smoking for those who want to get rid of this addiction.

«It is safest not to smoke. But if the person is not able to give up Smoking (disease!) and selects the method of dealing with addiction, the scientific data clearly show that electronic cigarettes in comparison with tobacco is less dangerous, although not harmless. It is unlikely that weepy promote the «stop Smoking», but to reduce the harm to themselves and others through electronic cigarettes, apparently,» — says the psychiatrist, doctor of medical Sciences, Professor, Kazan Federal University, who expert Vladimir Mendelevich.

Weepy as conventional cigarettes contain a psychoactive substance (nicotine), and thus form an addictive, and it’s not just the psychological aspect.

«We know that nicotine addiction is one of the most severe and resistant to treatment, and the severity of the addictive potential of nicotine in third place out of fifteen drugs, second only to heroin and crack cocaine,» — says Mendelevich.

That is why electronic cigarette and useless in the fight against Smoking, experts believe the world health organization and the U.S. National cancer Institute. Moreover, according to the survey of employees of the Voronezh state medical University named after N. N. Burdenko, those who smoke VAPI, often observed the same high level of addiction to nicotine as the more conservative smokers.

«Talk about the dangers of electronic cigarettes, unfortunately, went beyond academic discussion. Too many lobbyists from both sides are trying to put science itself in the service. Sometimes you have to read in serious journals «reviews» with a decidedly selective approach to the analysis of the research. Therefore, the findings of scientists so different. But one thing the researchers consolidated: VAPI unsound», — said Vladimir Mendelevich.

Among the proven effects of the serious problems with the heart and blood vessels. In mice, which the American doctors were regularly forced to breathe the fumes of electronic cigarettes fairly quickly, the walls of the arteries and veins become brittle and this leads to the development of cardiovascular diseases.

Swedish scientists from Karolinska University observed similar changes in the human body. At fifteen young volunteers, vucurevich full vaping was having the same problems as that of the mice in American experiences: arteries narrow and lose flexibility. This increased the pressure and caused negative effects, typical for tobacco lovers.

In addition, inhaled while vaping smoke harms the most intimate of human DNA, increasing the risk of ever dying of cancer. On the other hand, vapers seriously affected the immune system e-cigarettes, particularly flavoured, is fatal to the monocytes. In the experiments of researchers from the University of Rochester (USA) these are the most important cells of the immune system are killed, and threw out a lot of signaling molecules that, in turn, gave rise to inflammatory reactions in the lungs.Enough to sell: scientists have proved the harm of electronic cigarettes© RIA Novosti / Alexander Wolfparade in fotomontagen dispelled the myth about the safety of nicotine electronic cigarettes
