Dear Running Doc: I have read with interest comments from smokers about being left alone while they smoke. Isn't there a health risk to others around people who smoke? — Matthew M, Rochester, N.Y. Thanks, Matthew. I was thinking the exact same thing. Secondhand smoke, also known as environmental tobacco smoke (ETS), is a combination of the smoke given off by the burning end of a cigarette (or pipe or cigar) and the smoke exhaled from the lungs of smokers. It is involuntarily inhaled by nonsmokers, lingers in the air hours after cigarettes have been extinguished and can cause or exacerbate a wide range of very bad health effects, including asthma, respiratory infections, and even cancer! A few facts provided by the American Lung Association (http://www.lungusa.org) illustrate the dangers: * Secondhand smoke has been classified by the Environmental Protection Agency (EPA) as a known cause of cancer in humans. * Secondhand smoke exposure causes disease and premature death in children and adults who do not smoke. Secondhand smoke contains hundreds of chemicals known to be toxic or carcinogenic. * Secondhand smoke causes approximately 3,400 lung cancer deaths and 46,000 heart disease deaths in adult nonsmokers in the United States each year. * Nonsmokers exposed to secondhand smoke at work are at increased risk for adverse health effects. Levels of ETS in restaurants and bars were found to be 2 to 5 times higher than in residences with smokers and 2 to 6 times higher than in office workplaces. * Since 1999, 70 percent of the U.S. workforce has worked under a smoke-free policy, ranging from 83.9 percent in Utah to 48.7 percent in Nevada. Workplace productivity has increased and absenteeism decreased among former smokers compared with current smokers. * Fifteen states — Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Maine, Massachusetts, New Jersey, New Mexico, New York, Ohio, Rhode Island, Washington, and Vermont — as well as the District of Columbia and Puerto Rico prohibit smoking in almost all public places and workplaces, including restaurants and bars. Illinois, Maryland, Minnesota, Montana, New Hampshire, Oregon, and Utah have passed legislation prohibiting smoking in almost all public places and workplaces, including restaurants and bars, but the laws have not taken full effect yet. * Secondhand smoke is especially harmful to young children. Secondhand smoke is responsible for 150,000 to 300,000 lower respiratory tract infections in infants and children under 18 months of age, resulting in 7,500 to 15,000 hospitalizations each year, and causes 430 sudden infant death syndrome (SIDS) deaths in the United States annually. * Secondhand smoke exposure may cause buildup of fluid in the middle ear, resulting in 790,000 physician office visits per year. Secondhand smoke can also aggravate symptoms in 400,000 to 1 million children with asthma. * In the United States, 21 million, or 35 percent of, children live in homes where residents or visitors smoke in the home on a regular basis. Approximately 50 to 75 percent of children in the United States have detectable levels of cotinine, the breakdown product of nicotine, in the blood. * The current Surgeon General's Report concluded that scientific evidence indicates that there is no risk-free level of exposure to secondhand smoke. Short exposures can cause blood platelets to become stickier, damage the lining of blood vessels, decrease coronary flow velocity reserves, and reduce heart rate variability, potentially increasing the risk of heart attack. So runners, unite. Don't be passive when around friends who smoke. They are harming you as well as themselves and others.
