CORVALLIS — Students at Oregon State University in Corvallis started their school year this week on an entirely smoke-free campus.

Smoking had been prohibited inside buildings. Now, smokers must go outside the campus boundaries if they want to light up. A group of students started pushing for the ban about five years ago.

OSU estimates about 1,400 of its students and staff members are smokers.

A university spokeswoman says OSU has been educating staff and students about the change for some time. Those who are caught lighting up on campus risk a $30 fine.
