> "less than 2 drinks a day"

"less than 2 drinks a day" would be called "moderate drinking" in my culture. I mean if someone is having a drink or two everyday that is moderate drinking already.

Light drinking for us would be like 3 drinks in a week! 4 drinks/week or more gets us into the moderate drinking territory.

To be fair, "less than 2 drinks a day" covers any range below the upper limit of 2 a day, and hence also includes what you consider light drinking in your culture.

I suppose that the root of the matter is whether or not the range '>0 to <2 drinks a day' on average is too broad and may be hiding a significant difference of outcomes between the top of the range at 2 a day and the (non-abstinents) at the bottom who drink an average of, say, 2 drinks a week.

And that's not even going into regularity. I'm sure that 2 drinks a day on the regular has different health impacts and social implications than 14 drinks a night only on Fridays.
