non-alcoholic beer can usually only contains 0.5% alcohol by volume (abv), which is significantly lower than the 5% abv found in ordinary beers. This low alcohol content means that drinking non-alcoholic beer will not give you a high blood alcohol concentration (BAC), and therefore, you are unlikely to feel drunk or intoxicated.
In scientific terms, being drunk refers to having a certain level of alcohol in the bloodstream that affects your judgment, coordination, and overall behavior. A normal BAC for most people is around 0.08%, which corresponds to the effect of just a couple of drinks. At this level, you might start to feel relaxed, happy, or sociable, but you would still be able to perform daily tasks and drive legally.
since non-alcoholic beer contains such a low amount of alcohol, drinking several cans of non-alcoholic beer would be unlikely to cause a BAC high enough to make you feel drunk or impair your judgment. In fact, a 2012 study published in the journal alcohol and alcoholism found that even drinking 1.5 liters of non-alcoholic beer within an hour resulted in a BAC of less than 0.01%, which is well below the legal limit for driving in most countries.
non-alcoholic beer is designed to be enjoyed in moderation as a low-calorie, healthier alternative to regular beer. while non-alcoholic beer may not give you a significant buzz, it still offers a pleasant taste and can be a socially acceptable option for people who choose to limit their alcohol intake or avoid the negative effects of excessive drinking.
