I didn't only mean romantic relationships, but family relationships and friendships. I'm sure there are plenty of non-addiction-related reasons for being single!

It's interesting about the familial relationships. My father is pretty far along the religious spectrum and I am not, however we get along just fine. Of course the alcohol is something of a taboo and there have been certain frictions in between my life choices and his (such as the drinking and piercings/tattoos) however overall the relationship is still what I'd consider stable.

I realize I might have taken this a bit too personally and lost track of the overall theme. I do agree that judging the effect of certain vices could also be judged by more than just "does it affect your livelihood".
