Can You Get Drunk on Alcohol-Free Beer?

It's one of the most-asked questions about alcohol-free beer, and the answer is reassuringly simple once you do the maths.
The maths
A 330ml alcohol-free beer at 0.5% ABV contains only about 0.17 units of alcohol. A pint of ordinary 5% lager contains around 2.8 units. So you'd need to drink roughly 16 alcohol-free beers to take in the alcohol of a single strong pint — and you'd have to do it faster than your body removes it, which simply isn't realistic.
Your body keeps up
The average adult processes a bit under one unit of alcohol an hour. At 0.5%, the trickle of alcohol going in is roughly matched by what your body clears, so it never has the chance to build up to the level that causes intoxication. That's the core reason you can't meaningfully get drunk on it.
0.5% versus 0.0% — the one thing to know
In the UK, ‘alcohol-free’ can legally mean anything up to 0.5% ABV, so not every alcohol-free beer is truly zero. For almost everyone that trace is negligible, but if you need to avoid alcohol entirely, choose a beer labelled 0.0% and check the label. We explain the thresholds in is alcohol-free beer actually alcohol-free?
What about that relaxed feeling?
Some people feel a little looser after an alcohol-free beer. That's the ritual, the taste and the association at work — a placebo-like effect — rather than the alcohol, of which there's far too little to have a real effect.
Frequently asked questions
How much alcohol is in alcohol-free beer?
0.5% ABV or less in the UK, and many are 0.0%. For comparison, ordinary lager is around 4–5%.
How many alcohol-free beers equal one normal beer?
Roughly 10 to 16, depending on the exact strengths — and you couldn't drink them quickly enough to match the effect anyway.
Is 0.5% beer completely alcohol-free?
Not quite — 0.5% contains a trace of alcohol. If you want a true zero, look for a beer labelled 0.0%.
