Anyone who drinks more than a few times a week in the US is likely an alcoholic. Put someone in the hospital and have them discuss their usage with nurses over a variety of days... you will get quotes like (1-2 per week and 1-2 per day out of the same person) then you will have a nurse ask what their weekend drinking looks like and they will say "around a six pack"

Just my observations, maybe I work in a depressed part of the state.
