A state report says Iowa's tobacco tax revenue has dropped more than 9 percent since 2008.
Iowa Department of Public Health spokeswoman Polly Carver-Kimm said that she hopes the revenue is down because fewer people are smoking.
About 16 percent of adult Iowans were smokers in 2010, the most recent year for which trend data are available. The figure was about 20 percent in 2007, the same year state cigarette taxes were raised $1 a pack.
State fiscal analyst Shawn Snyder cited two key factors influencing Iowa tobacco tax revenue: Iowa's ban on smoking in most public places, which took effect in July 2008, and the federal government's 2009 cigarette tax increase of 62 cents a pack.
