How does condo association or HOA deal with smokers in building?

I am part of a condo association that has no rules or bylaws regarding smoking that takes place in an owner's unit. One of the units contains a family of smokers and the smoke is making its way into the other units that make up the common building. Since this is not addressed in the condo bylaws is there recourse by going to the county or state? What, if anything, is the responsibility of our Board of Directors with this issue?
