Would be a fun experiment…get a bunch of college kids and divide into two groups with half of them drinking non-alcoholic beer. Neither group knows what they are drinking except that its beer…see what happens.
I had a can of sharps when I was pretty young and until somebody told me it was non-alcoholic I could have sworn I was getting a buzz
My understanding is that none of those beers are totally non alcoholic. All have at least a fraction of a percent. So I suppose if you drank enough you could get drunk.
