If I found out the first or second visit, I probably wouldn't go back. If I was attached, it would affect me, but I'd probably stay. However, I'd lose a lot of respect for a T who smokes. Aside from the questions it would bring up about my T's mental faculties, I'd be worried that my T would develop cancer, or even just be more susceptible to respiratory infections. The worry about this really wouldn't help my anxiety, and I think I would grow to resent my T. Sure we all have our vices, but I just wouldn't have much confidence in a T who is actively engaged in a really harmful addiction and who had no intention of stopping.
