LOS ANGELES -- After 40 years of continual declines, the smoking rate in the United States has stabilized for the past five years, with one in every five Americans still lighting up regularly, the Centers for Disease Control and Prevention said Tuesday.
Moreover, more than half of all children are exposed to toxic secondhand smoke and 98 percent of those who live with a smoker have measurable levels of toxic chemicals in their bloodstream, setting them up for future harm from cancer, heart disease and a variety of other ailments.
"If you smoke and have children, don't kid yourself. Your smoke is harming your children," Dr. Thomas R. Frieden, CDC director, said in a news conference.
Using products marketed as being less harmful is no panacea, he added. "All cigarettes kill equally, and we know that light and low-tar cigarettes are no less likely to kill you."
Despite the reduction in smoking over the past decades, Frieden said, smoking remains the No. 1 cause of preventable death in the U.S. Every year, an estimated 446,000 Americans die from smoking- related diseases.
The good news is that some states are making progress in combating smoking.
Utah has the lowest smoking rate at 10 percent, and California is second, with a rate just below 13 percent, according to the CDC figures.
Since 1986, adult smoking in California has dropped by about 40 percent and, as a result, lung cancer rates in the state have been declining four times faster than in the rest of the country.
In contrast, Kentucky and West Virginia have the highest smoking rates, with about 26 percent of adults lighting up regularly.
If all the states had cancer-prevention programs like California's and Utah's, Frieden said, 5 million fewer people would be smoking and at least 1 million fewer people would die. Currently, about $25 billion is available to states from cigarette taxes, but only $700 million of that is spent on smoking prevention.
Another reason for the recent lack of success in getting fewer people to smoke is that the tobacco industry has gotten better at sidestepping government efforts to minimize smoking, Frieden said.
Among its activities, he said, are targeting price discounts at kids to get them to start smoking and finding new ways to promote products, such as introducing flavored lozenges to get around the ban on flavored cigarettes.
According to the study, published in the CDC's Morbidity and Mortality Weekly Report, about 20.9 percent of adults smoked in 2005 and 20.6 percent in 2009. In 1997, about 36 percent of high school students smoked. That proportion dropped to 22 percent by 2003, but has since declined more slowly, to 20 percent in 2009.
Smoking is related to gender, educational levels and race. The study found that:
SBlt 24 percent of men smoke, compared to 18 percent of women.
SBlt Nearly half of those with a GED and a quarter of those with no high school diploma smoke, compared to only 6 percent of those with a graduate degree.
SBlt About 31 percent of those who smoke live below the poverty level.
SBlt Nearly 30 percent of multiracial adults and 23 percent of American Indian and Alaska natives smoke.
