Unless you've decided to begin drinking responsiblely again (or attempt to), there is no positive benefit to consuming so-called non-alcoholic beer. Just as light beer leads to regular beer leads to mixed drinks leads to hard liquor during the course of an alcoholic's disease progression, so will non-alcoholic beer lead to harder stuff eventually. That is unless you can drink in moderation, which most of you can't, which is why you're here in the first place--and if you could, you wouldn't be playing with non alcoholic beers, you'd be drinking regular drinks.
Alcohol content, measured by volume, is simply a number a drunk needs to figure out how many of a particular drink they need to get the desired buzz. Many people begin drinking budweisers on weekends... soon, they're downing a 6 pack a night to get that buzz. Before they know it, it's a 12 pack a day. When they need more and more, it soon becomes evident that beer simply won't cut it anymore, because the quantity they'd need to consume to acheive a stupor is no longer feasible. That's when they're intrigued with mixed drinks like OJ and Vodka, or whatever--they can drink less and get even more drunk than they did with beer, oh joy! But, sooner or later it dawns on them why bother mixing the booze with anything to begin with? Then you have a full-fledged, hard liquor drinking alcoholic, who measures their intake in fifths of gallons. What makes any of you think that consuming a drink that contains .5% alcohol won't lead you to the same place as beginning with a drink that contains 4.5% alcohol did? Will the journey be a little longer? LOL.
