Metabolism (elimination): Metabolism is the method by which the body processes alcohol and everything else a person eats or drinks . Some of the alcohol is converted to other substances (such as fat, as in "beer belly "). Some is burned as energy and converted to water and carbon dioxide. A small amount is excreted unchanged in the breath and urine. The liver metabolizes about 90% of the ethanol. The lungs excrete about 5% during exhalation (breathing out). Alcohol excretion by the lungs forms the basis for Breathalyzer testing. Another 5% is excreted into the urine.
n. 1) the condition of being drunk as the result of drinking alcoholic beverages and/or use of narcotics. In the eyes of the law this definition may differ depending on the situation to which it is applied. 2) In drunk driving (DUI, DWI) the standard of intoxication varies by state between .08 and .10 alcohol in the bloodstream, or a combination of alcohol and narcotics which would produce the same effect even though the amount of alcohol is below the minimum. 3) In public drunkenness the standard is subjective, meaning the person must be unable to care for himself, be dangerous to himself or others, be causing a disturbance, or refuse to leave or move along when requested. 4) Intoxication as a defense in a criminal case in which the claim is made by the defendant that he/she was too intoxicated to form an intent to commit the crime or to know what he/she was doing, the amount of intoxication is subjective but higher than for drunk driving. There is also the question if the intoxication was an intentional aforethought to the crime ("I wanted to get drunk so I had the nerve to kill her.") Thus, unintentional intoxication can show lack of capacity to form an intent and thus reduce the possible level of conviction and punishment, as from voluntary (intentional) manslaughter down to involuntary (unintentional but through a wrongful act) manslaughter. However, in vehicular manslaughter, the intoxication is an element in the crime, whether getting drunk was intentional or not, since criminal intent was not a factor. (See: vehicular manslaughter )
