What symptom might indicate someone is intoxicated?

Slow reaction time is a key symptom that can indicate someone is intoxicated. Alcohol and other substances impair the brain's ability to process information and respond quickly to stimuli. When someone is intoxicated, their motor skills are compromised, and it takes longer for them to react to situations that require immediate response, such as driving or navigating through a crowded area. This delayed reaction can result in dangerous situations, as it affects both their ability to make quick decisions and their safety and the safety of those around them.

In contrast, clear and articulate speech, excessive sweating, and a calm demeanor are not definitive signs of intoxication. Clear speech may suggest the person is sober, while excessive sweating can be attributed to various factors unrelated to intoxication, such as temperature or anxiety. Similarly, a calm demeanor does not necessarily correlate with sobriety, as some individuals may remain calm even when under the influence. Therefore, slow reaction time is the most reliable symptom associated with intoxication.
