Second Hand Smoke - Breaths of Death

I like to take a walk on a beautiful campus of a state university. The scenery is breathtaking, especially the autumn air. In a certain period of that year, I felt deep breathing deeply and breathed in the natural scent of the surroundings. But when I felt suddenly that the cigarette smoke swallowed me, my enjoyment ended prematurely. It looks a bit familiar. If you are a non-smoking student, this scene reflects the daily life of the smoking campus.

Did you know that you are smoking the same smoking constituent as a smoker as a non smoker? According to Daniel McMillan and James D. Thor, the passive smoker is second-hand smoke, that is, non smoker's smoke. The smoke contains over 400,000 toxic chemicals. More than 40 known or suspected carcinogens (carcinogen). There is no safe secondhand smoke exposure level and the potential toxic gas exists at a higher concentration of sidestream smoke (from directly ignited cigarettes, pipes or cigar smoke) than mainstream smoke (exhaled smoke) smoker To do. And nearly 85% of the smoke in the room comes from sidestream smoke. ("Youth smoking: Understanding of risk" and "Smoking")

If smoking is prohibited in public places, you can protect the lives of smokers and the public. Studies have shown that secondhand smoke leads to death. Secondhand smoke causes sudden infant death syndrome (SIDS), respiratory infections, and pediatric asthma attacks. In addition, second-hand smoke can cause heart disease and lung cancer in both smokers and non-smoking adults. According to the Centers for Disease Control (CDC), secondhand smoke contains at least 250 known toxic chemicals, more than 50 of which can cause cancer (CDC, 2009). In addition, "California Environmental Protection Agency estimates that adult nonsmokers in the United States cause about 3,400 deaths of lung cancer per year and deaths from 22,700 to 69,600 heart diseases annually" (CDC, 2009)
