The only Christian group that I know of (and they do not permit smoking or drinking) is the Mormon sorority and fraternity known as.....
Sorority-
Lambda Delta Sigma is sponsored by The Church of Jesus Christ of Latter-day Saints. (LDS corresponds with Latter Day Saints, i.e. Mormons)
and their Fraternity counterpart-
Sigma Gamma Chi
These are found at campuses with a large Mormon student population. However, I was told once that the various Brigham Young University campuses do not permit fraternities and sororities, including the above ones.
However, there is a BYU with an LDS sorority chapter (in Hawaii) so maybe I have it wrong.
