How quickly does alcohol affect the body after consumption?

Alcohol begins to affect the body almost immediately after consumption. Once ingested, it is absorbed into the bloodstream through the stomach and small intestine. This rapid absorption means that even small amounts can start to influence a person's physical and mental state within moments. Factors such as whether food is present in the stomach or the individual's metabolism can affect the speed of absorption, but generally, the effects of alcohol can be felt soon after drinking.

In contrast, other choices suggest longer time frames for effects to be felt, which do not align with the physiological reality of alcohol absorption and its immediate impacts on the nervous system and cognitive functions.
