How does alcohol primarily affect judgment and decision-making?

Alcohol primarily affects judgment and decision-making by impairing cognitive function, which ultimately leads to poor decision-making. When a person consumes alcohol, it can alter their brain's normal functioning, particularly affecting the areas responsible for judgment, reasoning, and impulse control. This impairment can result in a lack of awareness of risks and consequences, causing individuals to make choices they may not make when sober.

For instance, someone under the influence of alcohol might underestimate their level of intoxication, leading to decisions like driving or engaging in risky behavior. Understanding this effect is crucial for alcohol sellers and servers, as they must recognize the signs of impairment and take appropriate action to ensure the safety of their patrons and the community.
