Smoking rates are the lowest in /*San Marino*/ with 5.3 percent and /*Malibu*/ with 5.8 percent of residents lighting up.
"Smoking is the leading cause of preventable death in the U.S. and is a major risk factor for cardiovascular disease, respiratory diseases and many cancers," explains Dr. Jonathan Fielding, the director of public health of Los Angeles County.
Fielding says more than a million adults in /*Los Angeles County*/ risk their lives and endanger the lives of loved ones with their smoking. He says understanding where smoking rates are high will help officials know where to target anti-smoking programs.
The city of /*Glendale*/ says the report is based on 2007 data that doesn't reflect its anti-smoking campaign. It objects to the findings that reveal that 15 percent of Glendale residents smoke. Glendale launched a major effort to curtail second hand smoke in 2008.
The American Lung Association has given Glendale an "A" grade for its anti-smoking program for two years.
