I have to agree with tiptopmanager. Being a former smoker, I wouldn't want to get back into a bad habit and living with a smoker would be too much of a teaser not to start again; however, for a non-smoker, I'd say, if the smoke doesn't bother you so much and you come up with some good ground rules with the smoker roommate, you may be able to work something out. I'm not really sure how playing the drums would influence living or not living with someone who smokes. (It's really your clothes, hair, furniture and air in the house that suffer when someone smokes inside.)
