Many active smokers think that the health of passively inhaling the smoke from cigarettes of people is not in danger. However, this is not the case. Moreover, a special substance of tobacco smoke called "acrolein" (chemical name - "aldehyde acrylic acid") has a high toxicity and leads to the development of cancer pathology.
WHO reports that during each year about 600 thousand people die from the causes associated with the passive inhalation of cigarette smoke. A group of specialists from the University of Vienna (Austria) was lucky to determine why tobacco smoke is so damaging to a living organism. It's all about the acrolein it contains. The effect of the compound was repeatedly tracked and repeated by scientists in experiments on white laboratory mice.
This volatile aldehyde has the ability to directly inhibit the activity of so-called T-lymphocytes, that is, the regulatory cells of our immune system. It is because of this "suppression" that the immune response of the human body ceases to be so effective as to prevent the growth of tumor formations. Of course, these mechanisms do not pass simultaneously, it takes time to accumulate a harmful effect and manifest it in the form of cancer of a certain organ.
In addition, acrolein acts irritatingly on the mucous membranes of the respiratory tract and the eye, belongs to a group of extremely dangerous substances within the toxicological science.
If you think that breathing smoke only occasionally, you are protected from such a bad influence of acrolein, then you are mistaken. Even rare and small, but constant doses of cigarette smoke can trigger cancerous processes. Especially it concerns such passive smokers as relatives, friends and even pets of active smokers. Unfortunately, acrolein can stay on your clothes, household utensils, towels, bedspreads, curtains. Thus, the home of a smoker is no less dangerous for those who live with him or communicate with him.
It is worth noting that acrolein can be useful to some extent: scientists have determined its anti-allergic effect. But does the significance of such a connection exceed its harmful activity? These questions have yet to be answered by scientists after a series of experiments.
