Its interesting that the UK President urged people to report violators of the
tobacco usage ban (so the university can help that person).
Cannot wait to find out what the University is planning to do with or to alleged policy violators.
If the violator is a member of the faculty or an enrolled student, the University could probably impose punitive sanctions (e.g. a scolding by Ellen Hahn, mandatory
tobacco treatment classes, being put on probabation or fired, being suspensed/expellsed from school), any of which could create an unfavorable reaction if the public found out.
But if alleged violators simply deny using an e-cigarette or smokeless
tobacco (or even a cigarette), I don't see how the university could impose sanctions against the alleged violator. And if that occurred, the alleged violator could have a potential lawsuit (e.g. unlawful search and seizure, no evidence, or violating civil liberties).
If the violator is a university staff represented by a labor union, the labor union might be able to sue the university (as that's what occurred in PA after the PA State Agency for Higher Education, which runs 15 state owned universities, banned smoking at all campuses back in 2008). The PA labor relations board and the PA court ruled that PA State Agency for Higher education violated the collective bargaining agreement by issuing that policy without consent of affected labor unions.
If the violator(s) is(are) not affiliated with UK, there's really nothing the university can do.
I suspect that the UK doesn't have a policy against alcohol use on campus.
Can you imagine someone being cited for using an e-cigarette or smokeless tobacco at a UK football game as thousands of drunk spectators continue drinking at the stadium.
