United Tribes Technical College has banned tobacco on its Bismarck campus.
College President David Gipp signed the policy Thursday on the annual Great American Smoke Out.
He says the goal is to protect people from the harmful effects of tobacco while still respecting native traditions.
The policy that takes effect Jan. 1 prohibits the use of tobacco on campus properties, in campus-owned vehicles and at sponsored off-campus activities.
But traditional or sacred use of tobacco is still allowed.
Other tribal colleges that are smoke free include Fort Peck Community College in Poplar, Mont., and Oglala Lakota College in Kyle, S.D.
