Study: More Than 80% Of U.S. Homes Forbid Smoking

NEW YORK (AP) — Smoking is banned in more than eight out of 10 U.S. homes — nearly twice as many as two decades ago, according to a new government study.

The Centers for Disease Control and Prevention found smoking is even forbidden in nearly half of homes where an adult smoker resides, up from one in 10 households with smokers in the early 1990s.

CDC experts attribute the changes to shrinking smoking rates and altered attitudes.

"People no longer see it as socially acceptable to smoke around nonsmokers," said Brian King, a CDC expert on smoking issues.

The adult smoking rate fell from 25 percent in 1993 to 19 percent in 2011. Helping that trend has been a boom in smoking bans in restaurants, bars and other public places, King noted.

The home is the main place that children are exposed to secondhand smoke. The CDC says secondhand smoke causes breathing problems in children, and causes an estimated 41,000 deaths among nonsmoking adults each year, mainly through heart disease and lung cancer.

In the new study, the government surveyed adults in about 200,000 U.S. homes in 2010 and 2011. The results were compared to previous versions of the same survey. Participants were asked if members of their household were allowed to smoke anywhere inside the home.

The CDC released the study Thursday.

Over the past two decades, Utah consistently has had the largest proportion of homes where smoking is not allowed. About 94 percent of Utah households fall in that category in the most recent survey. Kentucky and West Virginia were lowest, with both under 70 percent.
