Less than one UK unit per day, with some days per week alcohol free. One unit is 10 ml of pure alcohol. Alcohol in the UK is sold with the percentage of alcohol by volume (ABV) listed. To find the units you multiply the serving size in litres by the ABV.

In the UK that's seen as "very low". Other countries have different cultures around alcohol.

There are problems with these numbers, because people tend to under-report how many drinks they've had, and how strong the drink was.

> In 2015 in England, 55% of men said that they had drunk in the last year and that their average weekly alcohol consumption was no more than 14 units.

> 64% of women in England said that they had drunk in the last year and that their average weekly intake was no more than 14 units.

> In 2015, 11% of men and 7% of women in England said that their average weekly alcohol consumption was more than 14 units but no more than 21 units.

> In 2015 in England, 12% of men and 6% of women said that their average weekly alcohol consumption was more than 21 units but no more than 35 units.

> In 2015, 4% of men and 2% of women in England said that their average weekly alcohol consumption was more than 35 units but no more than 50 units.

This is important because there has been some publicity recently saying a drink a day is safe (mostly debunked now), or newspaper reports of the "benefits of red wine".

Here's one example of poor reporting: While we shouldn't increase the amount of pressure that pregnant women face (because they're already under considerable pressure) it's wrong to tell them that drinking wine daily is safe. https://news.ycombinator.com/item?id=6078575#6079665

Anything that results in a blood alcohol percentage between .12 and .15, it's that easy!
