I think that a ban on smoking on-campus should be considered simply because the majority of those I see smoking completely ignore the 25ft rule now. For those of us who have serious reactions to it or for those who just don't want to be around it, it is very unfair to have to walk straight into a cloud of smoke entering or exiting buildings on-campus. I have even been in an event hosted in a building on-campus where periodically the room would start to smell of smoke because of the people downstairs (outside) smoking right by the windows. Honestly, it is very inconsiderate. If no one is going to enforce the rule and smokers won't follow it, it should be banned.
