The snuff contains about 4,000 including 200 chemical substances harmful to health, which are released into the air every time someone smokes. Many studies show that secondhand smoke can have harmful effects on nonsmokers and even cause diseases like lung cancer.
Every time someone lights a cigarette, cigar or pipe smoke snuff the air comes from two sources. The first is the primary source, smoke the smoker inhales or puffs introduce when. Nonsmokers are also exposed to the primary source after the smoker exhales. The second, and even more dangerous source of smoke, is the secondary, which goes directly into the air from burning snuff.
Secondhand smoke inhaled-that a person who does not smoke every time is around someone who does, actually has higher concentrations of some harmful compounds than the smoke inhaled by the smoker. Studies show that there are several substances that cause cancer, as well as more tar and nicotine in sidestream smoke compared to the primary. In addition, carbon monoxide, which appropriates the blood oxygen may be from two to fifteen times higher in secondhand smoke.
Most of the smoke in a room is the result of secondhand smoke. When nonsmokers breathe air containing smoke cigarettes, cigars and pipes of other people, we say that the person is an involuntary or passive smoking.
The secondhand smoke and lung cancer
It is well known that cigarette smoking is the leading cause of lung cancer in smokers. In 1986 the Surgeon General of the United States reported that involuntary smoking can cause lung cancer in nonsmokers healthy. Recent studies also show that secondhand smoke causes death from heart disease.
What this could mean is that the snuff smoke and radiation can have this in common: there is simply no safe levels of exposure.
Effects on children
Second-hand smoke is especially harmful effects on infants and children whose parents smoke. Several studies show that in its first two years of life, babies of parents who smoke at home have a higher rate of lung diseases such as bronchitis and pneumonia, much higher than babies whose parents smoke.
A study of children aged between five and nine years, showed the existence of impaired lung function in young people who had parents smoking, compared with those whose parents did not smoke. Smoking in pregnant women seems to be that predisposes preterm infants respiratory distress syndrome.
Parents who smoke at home can aggravate symptoms in some children with asthma, and even cause asthma attacks. Parents should only smoke outside the home or, better yet, quit.
A team of researchers found that even in children without asthma in young age and whose parents smoke, acute respiratory diseases occur twice as often compared to children of parents who do not smoke.
