Opinion on smokers?

Smoked since I was 11, had to quit 4 years ago when I was admitted into the hospital with heartproblems. Did so radically but I also allow people to smoke in my house. In my opinion it was the only way to make sure I could deal with the temptation. Anyways I didn't turn into an anti smoke nazi. (but I'm amazed by how smelly it is now my olfactory system seems to work again)
