How many units per week is safe?

UK Chief Medical Officers recommend no more than 14 units per week for both men and women, spread over 3+ days, with at least 2 alcohol-free days. This equates to about 6 pints of average beer.

How long does alcohol take to leave your body?

The liver processes about 1 unit per hour. A person who has drunk 4 units will take approximately 4 hours to eliminate the alcohol — though this varies by weight, sex, and food consumed.

ABV (Alcohol By Volume) is the percentage of the drink that is pure alcohol. Beer: 4–6%. Wine: 11–14.5%. Spirits: 37.5–40%+. Shown on all labelled drinks.
