A new survey shows fewer Iowans are lighting up. A new report from the Iowa Department of Public Health shows the number of adult Iowans who smoke cigarettes has dropped 22-percent since 2006. Preliminary results show that 14-percent of adult Iowans, or about 327-thousand people, say they smoke cigarettes. That's down from more than 400-thousand two years ago. Concerns over their health was the number one reason given as to why they quit smoking. Cost was a distant second.
