My wife is a smoker also. In her car we keep baking soda in the ash tray. When she snuffs out a cig, she snuffs it in the soda. About 4 times a year I open the hood with the engine running and spray a special cigarette cleaner (found at wholesale cleaning supplies store) into the two air intakes under the front window. The odor builds up on the evaporator. Her car never smells of smoke. Another trick is to take an old sock, soak it in vinegar and hang it inside making sure that there is a drip container and leave it over night. Smell gone. And of course every one having a fit over cigarette odors think nothing of exhaust fumes loaded with carcinogens and unburnt hydrocarbons!
