New replacement of cigarettes was recognized as dangerous


Scientists from Australia and India found out that the systems of heating of tobacco are also toxic for cells of lungs, as well as usual cigarettes. Article of experts is published in the ERJ Open Research magazine. Researchers tested the system of heating of Iqos tobacco and also usual and electronic cigarettes on two types of cages of a respiratory system of the person — bronchial the epitelialnykh and cells of smooth muscles. Epitelialny cages provide the first defense line from the foreign debris getting into airways, and smooth muscles support functioning of lungs. The cultures of fabrics treated to action of tobacco smoke, steam from an electronic cigarette and aerosol from the system of heating of tobacco. It turned out that smoke from cigarettes and aerosol from the system of heating of tobacco are toxic for lungs, killing cages even at low concentration, and steam from vapes shows toxic properties only at rather high concentrations. Thus, use of systems of heating of tobacco increases risk of development of serious diseases, including a chronic obstructive pulmonary disease, pneumonia and cancer. In the systems of heating of tobacco (heat-not-burn tobacco product, HNB) there is no combustion of contents as the device maintains temperature below that that is used for smoking of usual cigarettes. Iqos, Glo and other similar systems emit the smoke containing nicotine and other chemicals. It is supposed that the lack of process of burning does not lead to release of the cancerogenic substances which are formed at combustion of tobacco though a number of researches showed that it not so.
