Which symptom is characteristic of alcohol intoxication?

Slurred speech and impaired coordination are hallmark symptoms of alcohol intoxication. When a person consumes alcohol, it affects the central nervous system, leading to a decrease in motor control and cognitive function. This impairment is often observed through noticeable slurring of words, an inability to maintain balance, and difficulties in performing physical tasks. These symptoms can vary based on the amount of alcohol consumed and the individual's tolerance level, but they are consistently recognized as indicators of intoxication.

In contrast, severe anxiety and hallucinations are more aligned with withdrawal symptoms or other substance use disorders rather than intoxication. Extreme euphoria and elevated mood, while they may occur in some individuals under the influence, are not universally characteristic of alcohol intoxication, as the effects can range from relaxation to depression, depending on the individual's state and context. Finally, increased energy and hyperactivity are more commonly associated with stimulant substances rather than alcohol, which typically has depressant effects. Overall, slurred speech and impaired coordination are the definitive signs that signal a person is intoxicated by alcohol.
