What is Blood Alcohol Concentration?

Blood Alcohol Concentration (BAC) is the amount of alcohol in the bloodstream. Alcohol is absorbed into the bloodstream through the stomach walls and the intestines as a person drinks. The bloodstream carries the alcohol to the brain and alcohol is then transported in the blood stream to the liver, which breaks down the alcohol., but can only manage approximately one unit an hour. As more alcohol is consumed the BAC rises. However the exact time that the body takes to absorb alcohol varies from one person to another. Click here to find out more 

Blood alcohol concentration is used by the police to test how much you’ve been drinking. A BAC of 0.08  means that an individual has 0.08g of alcohol in their body for every 100ml (0.1L) of blood.

Be careful to check drink-drive laws if driving abroad as BAC limits vary from country to country. The USA and UK have a BAC maximum of 0.08g, whereas most of Europe has a limit of 0.05g (In Sweden it is 0.02g).

In Malta the BAC level is 0.08g.
