Likening this to the "wage gap" where the XY chromosome is responsible for more outlier behavior: both the top of society and the bottom is both heavily dominated by male participants, whereas the female population is closer to the average and has far fewer outliers. Could this be related?
There's variance in XY chromosomes that cause men to swing wildly on the scale in both positive and negative directions. There seems to be an answer to the hypothesis that asserts that individuals with wildly differing attributes seem more often than not to fall on the outside of the law.
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".
E: to amend that, I do have a small group of close male friends but I do have trouble finding an intimate relationship, due to other (unrelated? maybe?) issues with women.
I would say that my love of alcohol and wine in particular would qualify as an addiction; but at the same time I'm able to hold down a job. My bosses are happy with my work and I do feel fulfilled with what I've accomplished at the end of the workday.
I'm sure psychologists would have a field day with me but as far as your original question I've offered my input.
