More U.S. households smoke-free, study says

ATLANTA (Reuters) - Nearly twice as many U.S. households are smoke-free compared to 20 years ago, reflecting an increased awareness of the health hazards from secondhand smoke, but too many people still are exposed, according to a federal study released Thursday.
In the early 1990s, 43 percent of U.S. homes were smoke-free, a figure that rose to 83 percent in 2010-2011, according to the study, issued by the Centers for Disease Control and Prevention.
More than 90 percent of homes without a smoker and nearly half of those with at least one adult smoker had smoke-free rules, the study said.
"It’s a shift in social norms," said Brian King, lead author of the CDC study. "People no longer see smoking around non-smokers as socially acceptable behavior."
Still, he said, more progress is needed, particularly in homes where smokers live, as secondhand smoke from cigarettes kills an estimated 41,000 non-smokers annually.
“We know there is no safe level of secondhand smoke,” King said. “The ultimate goal is to not expose people to a known carcinogen.”
The increased number of smoke-free homes is attributable in part to the diminishing segment of Americans who smoke.
Some 18 percent of Americans were smokers in 2012, down from 42 percent in 1965, the CDC said. Continued...
