can 1 alcohol get you drunk?
In theory, 10 x 0.5% beers equal one 5% beer. However, you can't get drunk on non-alcoholic beer (up to 0.5%) if you're a healthy adult. Most people start to feel minor effects of alcohol – such as feeling relaxed and a minor impairment of reasoning and memory – when their blood alcohol content (BAC) reaches 0.04%.
