Depends on the beer. Measuring one beer as we donin Bavaria, in at least half litres, and meaning by multiple times a week more than three days, maybe. By measuring beer in 0.3 and 0.2 litres, ans assuming the average US beer, even doing so 5 days a week propably doesn't get into abuse territory by the alcohol amount alone.

In US culture/science, one "drink" or "beer" is 0.5oz of alcohol. Beer is often 12oz of 4% alcohol. Wine is 6oz of 9%. Liquor is 1oz or 50%, etc.

There are stronger drinks, but in this scientific context should be considered multi-drinks.

People not understanding this unit scale causes a lot of problems, like teens having 20-30oz pours of alcohol like it's (also ugh) soda or juice.

I wonder if European science and US science get muddied due to different "drij" sizes.

I can't speak for all of Europe, but in Austria no-one speaks of "drinks" when talking about alcohol consumption. This concept of a standard "drink" size is foreign to me and I know it only from US literature.

The average beer is closer to 5%, few wines are as low as 9% and nearly all mainstream liquor is exactly 40%.
