Despite the fact that the harm of cigarette smoking have long been proven, many smokers still convince themselves and others, that from one cigarette will not harm.But recent studies have shown that even very low dose of nicotine can cause irreparable harm to the human body.
This applies to smokers and those who are close, breathing in secondhand smoke.Research taking place in the medical college Weil Cornell, in the U.S., have shown that smoking is detrimental to the cumulative nature, which makes it dangerous even for passive smokers. They have every chance of getting obstructive pulmonary disease or even cancer.
To study the material was selected out of 121 case histories of patients Pulmonology.Are mostly active smokers with experience, but there were those who did not smoke at all. For the purity of the experiment was originally there was no evidence that person smokes or not. The study began with a urine test to detect nicotine in it. Based on the previous discovery of the effect of nicotine on the genes responsible for activities of lung cells, scientists can identify potential health problems in the patient. If the genes are damaged, then the respiratory system does not operate normally. Thus, we can diagnose serious illnesses associated with the
respiratory system and lungs are still at an early level where you can take preventative action.
It is noteworthy that more than 90% of urine samples containing nicotine, though less active smokers from the total number was not observed. Quite expected was the result of mutations in the passive smokers, which was confirmed in practice. It's safe to say that there is no "safe" number of cigarettes smoked greater than zero. But to people accustomed, that is around them smoke, is thoughtful - is it really worth your health, consider dividing those who consciously ruining your health?
