As a student....I have the following for you
Man....I go back the 20th :P
Fun times.... Fun times....
I say it will be fine. I smoke on campus ALL the time. Campus security is fun. They always come up and ask what flavor I have in there.
Just some advice...if someone comes up to you and is curious...dont jump to conclusions that they will be jumping to conclusions....it makes matter so much worse!
Just stick with the general smoking rules. ( no smoking inside or like 30ft from a building). You should be ok
