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 grams of alcohol per liter of blood. [1] [2] In different countries, the maximum permitted BAC when driving ranges from the limit of detection (zero tolerance) to 0.08% (0.8 ...
Symptoms of varying BAC levels. Additional symptoms may occur. The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), to stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses.
[121] [122] It is less accurate for BAC levels below 0.2 g/L (alcohol is not eliminated as quickly as predicted) and consumption with food (overestimating the peak BAC and time to return to zero). [ 123 ] [ 93 ]

After binge drinking, unconsciousness can occur and extreme levels of consumption can lead to alcohol poisoning and death (a concentration in the blood stream of 0.40% will kill half of those affected [33] [medical citation needed]). Alcohol may also cause death indirectly, by asphyxiation from vomit.
Levels of even less than 0.1% can cause intoxication, with unconsciousness often occurring at 0.3–0.4%. [71] 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 ...
