3 drinks a day everyday is not healthy. If you’re on 3 a day you’re on the train to 7 a day and alcoholism.
These are usually reported as averages, not floors. I’m interpreting it as “21 drinks per week.” “At least 3 drinks every single day” is a much more serious problem IMO.
7 drinks a day is a fifth of vodka every other day. That’s at the point where you’re likely driving drunk regularly, and need to spike your morning coffee to stop the shakes.
I’d be less annoyed if they just said “3 or more drinks a day.” Putting the 7 there is designed to frame the problem as more severe. Imagine if the range said “3-17 drinks per day” instead. Then it would be too obvious what they were doing.
