For what it's worth dept. My Honda was owned by a smoker before I got it. While standing at the checkout counter at Discount Auto with some deodorizers, a man next to me identified himself as a HVAC tech. He said that they used a highly concentrated mix of vanilla extract (the real stuff) and water sprayed directly into air ducts to kill smoke smell from fire damage in buildings. I tried it and it definately helped in my car. Give it a try. Wipe down the upholstry and spray into carpet. Worst that can happen is you'll have an uncontrollable desire to stop at every Dairy Queen and Baskin Robbins.:p
