This song sounds like, to me, someone who got into deep trouble (the title implies smoking, but it could be anything like sex or alcohol or gambling, or anything really like that) and their friend is trying to figure out what is going on in this person's life.

"All I wanted was the real you" seems like this friend is trying to dig deep and find this person's secret, and then the bridge

"This is a conservation, that we only learn to live, and it make it alone, but it can't really work."

shows simply that we can't make it in the world by holding everything into ourselves, we have to tell our friends or else we'll kill ourselves from the inside.

I really love how the chorus is worded "If I was blind, said that everything's fine, would you kick me out the back door, or would you show me what i'm looking for."

like the last line in particular. This friend is waiting for this hurt individual to confess what's going on.
