Inthe surgeon general estimated that secondhand smoke causes the premature death of 41, adults and more than infants each year. Secondhand smoke is classified as a Group A carcinogen, a substance known to cause cancer in humans and animals. Secondhand smoke is a mixture of smoke released by the burning end of cigarettes, pipes or cigars, and smoke exhaled from smokers, which can be involuntarily inhaled by nonsmokers.
It contains more than 7, chemical compounds, 69 of which are known to be carcinogenic to humans or animals. Here are some known carcinogens found in secondhand smoke: In contrast, only Almost half of middle and high school students Nearly 25 percent While less toxic than smoke from cigarettes, e-cigarettes emit many potentially toxic substances and research is still being gathered on the harmfulness of exposure.
Although secondhand smoke exposure among youth with asthma declined between andthe majority were still exposed, with higher exposure among low-income youth.
Nearly 15 percent More than 15 percent The percentage of homes that are voluntarily smoke-free has been rising. Between and83 percent of adults reported they lived in a home where smoking indoors was not allowed, a 93 percent increase from andwhen 43 percent of people reported living in a smoke-free home.
Smoke-free homes, however, are more common among people with higher levels of education throughout all racial and ethnic groups and in states with lower rates of adult smokers. Department of Housing and Urban Development has mandated that all public housing agencies adopt a smoke-free policy by July 31, The policies must prohibit the use of combustible tobacco products in all indoor areas, living units and office units — and within 25 feet of these areas.
More than 8 percent 8. Nonsmokers exposed to secondhand smoke in cars are at an increased risk of cancer.
From to Separating smokers from nonsmokers, cleaning the air and ventilating buildings does not effectively eliminate exposure. Smoking bans in the workplace and in public venues inspire similar voluntary policies in homes. Blue-collar workers are more likely to be exposed to secondhand smoke at work.
Some researchers have surveyed indoor environments exposed to secondhand smoke and found multiple compounds lingering on furniture and other surfaces, such as nicotine and even carcinogenic nitrosamines.
Additional research is needed on THS to understand the full breadth of potential health effects — especially for infants who are likely to place their mouths on objects in their environment, leading to oral exposures of THS compounds. Secondhand smoke can cause lower respiratory illnesses including pneumonia and bronchitis and persistent adverse effects in lung function during childhood.
Children with asthma who are exposed to secondhand smoke are more likely to have compounding health conditions such as obesity and severe asthma. They are also less likely to visit a health care professional. Recent research suggests a connection between secondhand smoke exposure in children and adolescents and an increased risk of developing mental health issues, such as major depressive disorder.
ADULTS Secondhand smoke exposure among nonsmokers is responsible for an estimated 7, lung cancer deaths and 34, cardiovascular disease deaths annually. Exposure to secondhand smoke can increase the risk of cardiovascular disease by 25 to 30 percent and the risk of lung cancer by 20 to 30 percent in nonsmokers.
Secondhand smoke increases the risk of stroke in nonsmokers by an estimated 20 to 30 percent.
Deaths caused by secondhand smoke have a disproportionate impact on African-Americans and Hispanics. More than 42 percent of the population is not protected by comprehensive smoke-free laws. Lower-income communities are less likely to be protected by smoke-free laws. Many multi-unit housing communities have begun to implement smoke-free policies to protect residents from secondhand smoke, which can infiltrate homes from neighboring units.
Department of Housing and Urban Development is requiring all public housing agencies to enact a smoke-free policy by July 31, Secondhand smoke Eliminating secondhand smoke by enacting smoke-free protections is necessary to reduce the number of deaths, illnesses and losses of productivity that result from exposure each year.
States and localities should pass comprehensive clean indoor air measures that prohibit smoking in all workplaces and public facilities, including restaurants, bars and casinos, to provide protection to all people against the serious dangers of secondhand smoke.
Most e-cigarettes and other electronic nicotine delivery systems emit many potentially toxic substances and should be included in clean indoor air laws. While vapor from such devices is substantially less harmful than smoke from combustible tobacco, there is not enough evidence on the health impact of the potentially toxic substances in secondhand vapor to justify an exemption in the law.
States and localities should enact further smoke-free restrictions in community settings, such as building entrances, restaurant patios, strip malls, parks and bus stops, to reduce secondhand smoke exposure. States and localities should also pass laws making multi-unit housing, such as apartments and condominiums, smoke-free so that secondhand smoke does not infiltrate the units of nonsmokers.Effects of Secondhand Smoke: Facts.
