. VAPI and other types of electronic cigarettes cause the mass death of monocytes, cells of the immune system, particularly for evaporators with different flavors, according to a paper published in the journal Frontiers in Physiology.

«Now the sale of wapow not regulated, and «tasty» names of flavors such as caramel, biscuit, pushechny or mysterious, often attract young people. Our study shows that the sale of such fillers should be limited, and that their manufacturers should specify all of the components. We urge the authorities to protect public health,» said Irfan Rahman (Irfan Rahman) from the University of Rochester (USA).

In the last two years, due to the rapid growth of the popularity of wapow among smokers, scientists have been interested in whether such evaporators are those useful properties, which they attribute to their manufacturers, and how they are less harmful than regular cigarettes.

These studies have led to conflicting results – overall, tobacco smoke is more dangerous to the health of the lungs and the body, but the evaporation of electronic cigarettes, as recently discovered by scientists, contain numerous carcinogens and toxins, produced as a result of «burning» part of the evaporated liquid on the filament.

Rahman and his colleagues uncovered another negative property of these fluids, watching the steam produced by evaporation of different brands of nicotine liquid, affects the viability of several cell cultures.

As it turned out, similar liquid comprising aromatic additives, negatively impacted not only on the cells of the lungs, but also on certain types of immune cells. For example, even a relatively small amount of steam caused mass death of monocytes, one of the key types of immune cells, and forced them to throw large quantities of signaling molecules that cause inflammation and other reactions contributing to the effect of harmful substances from the vapor to the lung tissue.

Interestingly, the strength of these negative effects depended not only on the amount of steam, which contacted cells, but also on the type of filler. For example, the most harmful was liquid cinnamon flavor, watermelons and strawberries, and relatively safe fillers with fruit and coconut.

Such differences, as scientists believe, due to the fact that manufacturers of these nicotinic compounds is not always indicative of what is really contained in their products, and almost never check how these components interact among themselves and with human cells. In the near future, Rahman and his colleagues plan to see what long-term consequences of Smoking such wapow.
