Cigarette smokers are said to have a good chance of getting various fatal diseases. But, I think that other people's tobacco smoke seems to increase the chances of nonsmokers getting a wide range of cancers.
First, although passive smokers inhale less tobacco smoke, the researchers point out that the smoke you breathe in is richer in many toxic chemicals. There is, for example, three times as much as benzo-apyrene, six times as much toluene and more than 50 times as much dimethynitrosamine. Of course this substance will harm our body in the long run.
secondly,the recent research reported that the risk of getting cancers not normally associated with smoking also rose among passive smokers. The risk of leukimia rose 6-8 times and the risk of cervical cancer increased 3-4 times.
Thirdly, past studies have found that by product of cigarette smoke such as coinine and thiocyanate, turn up in the blood, urine and saliva of non-smoking adults, children and fetuses that have been exposed to smokers. These substances are the main causes of various cancers.
In short, the effects of exposure to the cigarette smoking of others are greater than has been previously suspected. That is why passive smokers have more chances of contracting cancer than people with now such exposure.
