According to an article in the Daily Athenaeum: "The policy states that signs will be posted marking non-smoking areas, and any students who violate the policy are subject to 'disciplinary sanctions, up to and including expulsion.'"
This seems like a pretty harsh sanction for placing a wad of chewing tobacco between your cheeks, especially when getting drunk by consuming a case of beer is almost certainly not treated with the same degree of harshness in punishment.
The Rest of the Story
Just two years ago, an undergraduate student at West Virginia University was killed by a fellow student who was driving while intoxicated. The accident occurred on campus, in a University garage.
Let me just say that in my opinion, the University has a lot more urgent matters to concern itself with in terms of "unhealthy" behaviors occurring on its campus.
It seems like it would be difficult to explain to the parents of this unfortunate victim of drinking on campus that the University has found it to be a priority to stop people from stuffing chewing tobacco in their mouths on campus.
