I know people who smoke to escape. They know it's killing them, we don't need to tell them that. What if that was the point of them taking up smoking in the first place?
Well if that's the case, if I knew a person like that I'd probably try to help them and make them feel better. I'd honestly do anything to help someone. Smoking to me is a big deal tho, I know some people don't take it that seriously but I really do.
