I'm a smoker, is this affecting my body and mind?

I’ve tried to quit before, but its just so nice to have a cigarette sometimes,—-like after certain other earthly vices that I am not ashamed of.—-

Shaman, medicine men, and mystics in different cultures smoke tobacco, but is it really OK? Does smoking have any effect on our aura, spirit, soul, essence, etc?

I know that smoking is bad for my body, so I don’t need to be reminded of the health risks. I’m curious as to what the mystics out there have to say about this topic.
