NBC NATIONAL NEWS — A new report shows how apartment dwellers may be exposed to secondhand smoke, even if they themselves keep a smoke-free home.
Researchers at the U.S. Centers for Disease Control and Prevention estimate a quarter of all Americans live in multi-unit housing, like apartment buildings or condos, which is nearly 80 million people.
The report shows a majority don't allow smoking in their homes. However, nearly half are exposed to secondhand smoke that seeps in through the walls, windows and ventilation systems from other units in their building.
Secondhand smoke has been linked to a variety of health problems, ranging from asthma and ear infections in children to heart disease and lung cancer in adults.
