That really depends on which sect of Christianity you're talking about, and that buddy is basically looking into thousands of groups. In some countries priests who practice a certain form of religion still don't marry. Smoking though is a habit that is taken up by people of all backgrounds, creeds, and ethnic groups.

I find your question to be a bit random, it almost sounds like you're trying to dig up information about some people on this board whom you think might smoke when they shouldn't. Did someone on here offend you?
