WEST LAFAYETTE, Ind. (AP) — Smoking would be completely banned on Purdue University’s main campus in West Lafayette under a proposal from school President Mitch Daniels.

Smoking is already prohibited in residence halls and all other campus building, but Purdue designated 21 smoking areas around the campus in 2010.

The (Lafayette) Journal & Courier reports Daniels told the University Senate this week that he’s seeking feedback from employees and students about the smoking ban, but wants the group to make a final recommendation.

Purdue Student Government president Geri Denger says the change could drive more students to live off campus. She worries the smoking ban could hurt the school’s appeal to international students, who she said tend to smoke at a higher rate than U.S. students.
