If it is in your bylaws, don't smoke in letters.

Remember that when in letters or not in letters, you represent your organization. Your actions and words can be taken to represent the whole.

I agree-- Tough to enforce, but it is up to the individual to act in a matter that befits the letters she assumed when she accepted her obligations of membership.

ETA: per my chapter, we couldn't smoke on or around sorority grounds, in letters, or even in a car that had letters. Typically, the new members were scared out of their habit because it was impressed that every action you take reflects back on the chapter.

Whether this was a good way to instill a practice or not, we had very few incidences of members smoking and those who smoked were extremely discrete about where they smoked cigarettes.
