Having an air freshener in your car might scream drug dealer to the police. When somebody hangs these little Christmas trees from their rearview mirror, the police do look at that as maybe reasonable suspicion that you might be trying to mask a smell in your car. They may ask you to step out of your car and ask you for consent to search, which you would never give because you're a Dr. Judge follower. But just remember, clean your car out. I don't hang those things from my mirror, and I don't think you should. It doesn't matter if you disagree with me if it leads the officer to reasonably suspect that you're dealing in drugs.
