Widener is one of a growing number of law schools that are getting tough on smoking by students, faculty, staff and visitors. Most law schools already prohibit smoking inside and near buildings, but at least three are preparing to become completely smoke-free campuses next summer. At least five already are. According to the American Lung Association, 176 colleges and universities in the United States are now fully smoke-free.
