The best way to keep your car's interior from smelling like cigarette smoke is to make sure that you don't smoke in your vehicle, or at least not near it. If you must smoke while driving, open a window or turn on the air conditioning to help dilute the smell. You can also try using an air freshener to mask the scent of cigarettes if you're really worried about it.
