Blood alcohol content (BAC), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [1] BAC is expressed as mass of alcohol per volume of blood. In US and many international publications, BAC levels are written as a percentage such as 0.08%, i.e. there is 0.8 ...
First, a word about cause versus risk. On a cellular level, alcohol is carcinogenic due to the ways it damages cells. When it comes to a whole person, alcohol is one of many factors — which also ...
Binge drinking is defined as the amount of alcohol it takes to raise a person’s blood-alcohol concentration level to 0.08, the legal definition of being intoxicated in most states.
Promille and permille are likely best known as shorthand terms for Blood Alcohol Concentration, where 1 promille corresponds to 1 gram of alcohol per liter of blood. [8] Promille is used in the legal limits of blood-alcohol content for driving a road vehicle in some countries: for example: 0.5‰ or 0.8‰. [9]
In jurisdictions in the U.S., maximum blood alcohol levels for legal driving are about 17 to 22 mM. [ 67 ] [ 68 ] In the upper range of recreational ethanol concentrations of 20 to 50 mM, depression of the central nervous system is more marked, with effects including complete drunkenness, profound sedation, amnesia, emesis, hypnosis, and ...
It is based on the average rate at which someone can reduce blood alcohol concentration level, which is by 0.015 each hour (0.015 grams per 100 milliliters per hour).
For other countries, it may be easiest to convert to UK units. For example, in the United States one standard drink contains 14 grams ≈ 1.75 units of alcohol, and so a US standard drink takes the body about an hour and three-quarters to process. Blood alcohol content can more accurately be estimated by using Widmark's formula. [43]
To reach a blood alcohol level of .30, a person would have to consume at least six to seven alcoholic drinks in an hour, though this measure changes based on one’s weight and gender, according ...
