ABERDEEN - Students at Northern State University in Aberdeen have begun collecting signatures to bring a smoking ban to a campus-wide vote.

The college's student association is looking to collect 200 signatures to put the issue in front of students, faculty and staff.

Association president Kody Kyriss says the referendum was started because students are worried about their health.

The measure would ban people from smoking on campus, except in the university's parking lot.

The Aberdeen American News reports that Northern State and South Dakota State are the only public universities in the state that do not have a complete smoke-free policy.
