West's Encyclopedia of American Law | Drunkenness

The state of an individual whose mind is affected by the consumption of alcohol.

Drunkenness is a consequence of drinking intoxicating liquors to such an extent as to alter the normal condition of an individual and significantly reduce his capacity for rational action and conduct. It can be asserted as a defense in civil and criminal actions in which the state of mind of the defendant is an essential element to be established in order to obtain legal relief.
