Drunkenness is a physiological state that occurs when a person or animal has a high level of ethanol (alcohol) in his/her blood.
Common symptoms of alcohol intoxication include slurred speech, euphoria, impaired balance, loss of muscle coordination (ataxia), flushed face, vomiting, reddened eyes, reduced inhibition, and erratic behavior. In severe cases, it can cause coma or death.
Toxicologists use the term “alcohol intoxication” to discriminate between alcohol and other toxins.
Acute alcohol intoxication results from a very high level of alcohol in the blood. This term is used by health care providers, often in emergencies.
