Faculty members at Widener University School of Law will have a new role to play next academic year: smoking police.

They won’t have matching uniforms or extensive training. They will be armed with small cards that detail the school’s impending ban on smoking or using tobacco products anywhere on campus, indoors and outdoors. If that’s not enough to keep people from lighting up on campus, repeat offenders might be fined, said Linda L. Ammons, the law school’s dean.
