ST. LOUIS (AP) -- A new study shows that Jefferson County has the highest smoking rate in the St. Louis area.
The St. Louis Post-Dispatch reports that 30 percent of Jefferson County adults smoke, according to figures released last week by the University of Wisconsin Population Health Institute and the Robert Wood Johnson Foundation.
By comparison, just 18 percent of St. Louis County adults, 17 percent of St. Charles County adults and 9 percent of Monroe County, Ill., adults smoke.
Nationwide, the study shows that 19 percent of adults smoke. In Missouri, 24 percent light up.
