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 ...
Alcohol intoxication leads to negative health effects due to the recent drinking of large amount of ethanol (alcohol). [ 6 ] [ 20 ] When severe it may become a medical emergency . Some effects of alcohol intoxication, such as euphoria and lowered social inhibition , are central to alcohol's desirability.
Levels of even less than 0.1% can cause intoxication, with unconsciousness often occurring at 0.3–0.4%. [233] Death from ethanol consumption is possible when blood alcohol levels reach 0.4%. A blood level of 0.5% or more is commonly fatal. The oral median lethal dose (LD 50) of ethanol in rats is 5,628 mg/kg. Directly translated to human ...
The results of this study compared patterns of alcohol use from 2012-2013 to use in 2001-2002 and found that the rate of alcohol use rose more than 11%; the rate of high-risk drinking increased ...

[31] The high tolerance of chronic heavy drinkers may allow some of them to remain conscious at levels above 0.40%, although serious health hazards are incurred at this level.
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 ...
