What is the "legal" drinking age is not non-alcoholic beer in Ohio?
I wanted to go have some beers with a friend … im 21 years is 20 …. I did some reasearch and found out about o'douals, I think that's the way it is written … and wanted to know that it is legal drinking NA beer? I did some research and found that like alcohol containing 1% but then again to make some mouthwashes. and indeed what are some other brands? i do not usually drink and how we live in Ohio.
normal limit is 18, but some may vary
