Questions and Answers About Secondhand Smoke
Q: What is secondhand smoke?
A: When someone lights up a cigarette, cigar or pipe, they arent the only ones inhaling tobacco smoke. Other people in the vicinity of the smoker also inhale smoke in two forms side stream smoke (from the end of the burning cigarette) and the smoke exhaled by the smoker. Together, these form secondhand smoke. Breathing secondhand smoke exposes nonsmokers to many of the same dangers inherent in smoking a cigarette, cigar or pipe. Secondhand smoke is also called passive smoke or environmental tobacco smoke (ETS).
Q: What kinds of health problems does secondhand smoke cause?
A: Secondhand smoke causes a myriad of health problems, and even death, in both children and adults. According to the Centers for Disease Control, secondhand smoke is the third leading cause of preventable death in the U.S., killing 63,000 nonsmokers each year. For every eight smokers killed by tobacco use, one non-smoker is killed too.
In Children:
Secondhand smoke increases the chance that a child will suffer from coughs and wheezing, bronchitis, asthma, pneumonia, potentially fatal lower respiratory tract infections, eye and ear problems, or injury or death from cigarette-caused fires. Each year in the United States, 280 children die from respiratory illnesses caused by secondhand smoke.
According to a 1997 study, exposure to secondhand smoke leads to over 500,000 physician visits for asthma and 1.3 million visits for coughs, and to more than 115,000 episodes of pneumonia, 14,000 tonsillectomies or adenoidectomies, and 260,000 episodes of bronchitis. Exposure to secondhand smoke also causes two million cases of otitis media among children (an acute or chronic inflammation of the middle ear) and results in 5,200 tympanostomies (middle ear operations).
In Adults:
In non-smoking adults, secondhand smoke exposure causes approximately 3,000 lung cancer deaths each year. About one-third of these deaths can be attributed to secondhand smoke exposure in the home and about two thirds to exposures that occur at work and in public places. In fact, workers exposed to secondhand smoke are 34 percent more likely to get lung cancer.
Consistent with prior reports, a recent study (Steenland et al., 1996) for the American Heart Association found that people who have never smoked, but were currently exposed to secondhand smoke have about 20 percent higher coronary heart death (CHD) rates. Secondhand smoke causes nearly a quarter million heart attacks a year, one-fourth of them fatal.
Q: What makes secondhand smoke so dangerous?
A: Tobacco smoke causes many chronic diseases and even death for smokers and non-smokers alike. Thats because it contains over 4,000 chemicals including formaldehyde, cyanide, arsenic, carbon monoxide, methane, benzene and radioactive polonium-210. Tobacco smoke contains 43 known human carcinogens.
The Centers for Disease Control and Prevention (CDC) has concluded that smoke-filled rooms may have up to six times the air pollution of a busy highway. And secondhand smoke inside a car can be more toxic than rush hour exhaust fumes.
Q: What is a carcinogen?
A: A carcinogen is any substance that is known to cause cancer. The Environmental Protection Agency (EPA) and the U.S. Department of Health and Human Services National Toxicology Program both classify secondhand tobacco smoke among the most dangerous, or Group A, carcinogens.
Q: Is there research that demonstrates the dangers of secondhand smoke?
A: There are thousands of research studies that show the dangers of secondhand smoke. These studies have been analyzed and summarized in several major reports, including:
1986 The Health Consequences of Involuntary Smoking: A Report of the Surgeon General
1986 National Research Councils report entitled Environmental Tobacco Smoke: Measuring Exposure and Assessing Health Effects
1992 U.S. EPAs report entitled Respiratory Health Effects of Passive Smoking: Lung Cancer and Other Disorders
1997 California Environmental Protection Agency report entitled Health Effects of Exposure to Environmental Tobacco Smoke
2000 American College of Occupational and Environmental Medicine position statement entitled Epidemiological Basis for an Occupational and Environmental Policy on Environmental Tobacco Smoke
Q: Where can I get more information about the dangers of secondhand smoke?
A: For more information about the dangers of secondhand smoke, visit www.tobaccofreeny.org.
Q: What can I do to protect myself and my family from the dangers of secondhand smoke?
A: You and your loved ones have a right to smoke-free environments. Smoking is a choice, but breathing is not! There are a number of simple actions you can take to protect yourself and your family from the free-floating poisons found in secondhand smoke:
- Insist on your legal right to a smoke-free workplace.
- Patronize only smoke-free facilities and let them know the reason behind your choice.
- Dont suffer in silence. If secondhand smoke makes you uncomfortable or drives you out of a public place, let the management of the facility know why they are losing your patronage.
- Write or call your local and state government officials to let them know that you favor smoke-free legislation for public places and all workplaces.
