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) as it applies to 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) as it applies to 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) 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, where 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”). 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.
