You should talk to whoever's in charge of the accommodations. A smoking ban went in effect in Ohio last year, and our resident assistants (students who are in charge of the dormitories) basically had to send out a lot of e-mails and posted signs near the doors telling people where it was acceptable to smoke. Maybe the administration doesn't know people smoke inside or doesn't care, but if you make it known that it bothers you, they should definitely make the smoking rules clear.
