I always preferred the shot of whiskey and then the beer!

Just kidding....I'm an alcoholic, as Haz said, predisposed to have a problem because my Dad was a functioning alcoholic as were all of my four other siblings. We have all learned to control that problem. As I said before, it's a weakness in my opinion. For the record, I really didn't drink excessively.
Did smoking pot lead to other things, maybe but I never let any of that get out of control like the drinking. I can't find too many people my age that have not smoked pot. I know of none of my friends that went to become an addict of smack, crack or meth....etc....
Smart people can be guilty of doing stupid things! There are millions of people in this country that still smoke, lead normal lives and do no harm to any one but they just don't talk about it.
