TUESDAY, Sept. 6 (HealthDay News) -- The rate of smoking among U.S. adults has resumed its four-decade decline, and those who continue to light up appear to smoke less than previous generations, officials from the U.S. Centers for Disease Control and Prevention said Tuesday.
"For 40 years there was a consistent decline in the number of adults who smoked -- from 1964 to around 2005," CDC director Dr. Thomas R. Frieden said during a noon press conference releasing the results of the CDC's new report on smoking prevalence in the United States.
The downward trend stalled after 2005 and has since resumed, but at a pace "much slower than the rate of previous declines," he said.
The number of smokers age 18 and older inched down from 20.9 percent in 2005 to 20.6 percent in 2009 and 19.3 percent in 2010, according to the report. That's about 3 million fewer smokers than if there had been no decline, the researchers noted.
While the number of people who smoked a pack and a half or more a day fell substantially, those smoking less than a half pack a day increased, according to the report, which relied on data from the 2005-2010 National Health Interview Surveys and the 2010 Behavioral Risk Factor Surveillance System survey.
Smoking less doesn't save lives, Frieden said. "The only safe thing to do is to quit smoking entirely," Frieden said.
About 45 million Americans still light up regularly, the CDC said.
Smoking takes a significant health and economic toll, Dr. Timothy McAfee, director of CDC's Office on Smoking and Health, said during the press conference. "Smoking costs the U.S. about $193 billion annually, which is comprised of direct medical costs and lost productivity," he said.
Smoking bans, cigarette price hikes and aggressive media campaigns have proven to be effective tools in the war against smoking, the researchers said.
