I really dont know why anyone smokes. It is the most disgusting habit ever! So my patient the other day was a really nice lady and she was also my first patient that smokes. YIKES! I dont really like the smell of smoke but it never really bothered me that bad. Well out of all the patients that I have seen since the beginning of school this was the grossest by far. I had a mask on and everything but the smell was indescribable. Also she had dark brown stains on all of her teeth that took forever to get off. It was not pretty. Dont every smoke!
