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 ...
Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression or aspiration of vomit if vomiting occurs while the person is unresponsive. Emergency treatment strives to stabilize and maintain an open airway and sufficient breathing while waiting for the alcohol to metabolize.
Negative values of the decimal logarithm of the median lethal dose LD 50 (−log 10 (LD 50)) on a linearized toxicity scale encompassing 11 orders of magnitude. Water occupies the lowest toxicity position (1) while the toxicity scale is dominated by the botulinum toxin (12). [107] The LD 50 values have a very wide range.
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 ...
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.
This means that if an officers pulls you over and determines your driving has been impaired by alcohol or drugs, you could be arrested even if your BAC level is below 0.08%. More: 1 in 5 Wisconsin ...

The amount of alcohol consumed largely determines the extent of hangovers, although hydration also plays a role. After excessive drinking, stupor and unconsciousness can both occur. Extreme levels of consumption can cause alcohol poisoning and death; a concentration in the blood stream of 0.36% will kill half of those affected.
