Try something VERY simple first. Take an old tube sock; soak it up with white vinegar. You just want the sock to be damp with the vinegar, not really wet. Then hang it from the rear view mirror for a few days. You can do this in the evening after you have parked the vehicle for the evening. This way you don't have to drive around with a sock hanging from the mirror. It will not harm anything and absorbs many odors, especially smoke. You can use a longer rubber band to suspend the sock from the mirror.

You can repeat the process, but this really works.

It will even get rid of skunk odors, which is difficult to get rid of. My wife put the dog in one of our vehicles rather than in the house one time after he got into a skunk, and let me tell you...after a few choice words I used this method to get rid of the odor. It works!
