Nonsmokers face a variety of serious risks from exposure to other people's tobacco smoke. According to the Centers for Disease Control, secondhand smoke:

-- Causes 3,000 deaths from lung cancer and 62,000 heart disease deaths in U.S. nonsmokers each year

-- Causes serious respiratory problems in children, including increasing the frequency and severity of asthma attacks

-- Increases the risk of sudden infant death syndrome and middle-ear infections in children

-- Represents a common, severe public-health hazard that can be entirely prevented by adopting and enforcing tough antismoking regulations
