A new survey of adult smoking in Minnesota finds big disparities among the state's counties.
But Minnesota as a whole, along with neighbor North Dakota, ranks among the states with a relatively low percentage of adult smokers.
The Pioneer Press reports the smoking rates range widely.
For example, seven percent of adults in Nicollet County smoke, compared to 35 percent in Mahnomen County. Mahnomen County includes part of the White Earth Indian Reservation.
The survey found sixteen percent of Minnesota adults smoke. In North Dakota, 18 percent of adults smoke.
The rankings, released Tuesday, were compiled by the Robert Wood Johnson Foundation's County Health Rankings & Roadmaps program and based on federal behavioral risk surveys from 2006 to 2012.

Proponents of e-cigarettes say using the electronic devices can help smokers quit smoking.
The study, published in the journal JAMA Internal Medicine, found that smokers who also used e-cigarettes were no more likely to quit smoking after a year than smokers who didn't use the devices.
Some have questioned the small size of the study, which examined just 88 smokers who also used e-cigarettes.
