To smoke or not?

Went out with Brook, Lori, and Marianne tonight. We were at B & N till they closed and then headed to a pool hall in downtown Rochester. It was funny, an ex-quizzer came up to me. He looked like he was in college and wanted to say hello. He was suprised someone from DBQ was in there. Anyone who knows me, knows that I can ramble on and on about the state of Western Christianity. Seeing it there in detail though was a bit ironic. Why should a "christian" seem so out of place having a drink and a smoke in a pool hall? Would anyone in the New Testament have been concerned with that? If not, when did people start becoming concerned with it? If scripture had no problem with it, what were the motivations of those who began defining it as a problem?
