Final answer:
Alcohol affects a person's abilities depending on their blood alcohol concentration (BAC). The immediate effects can include feelings of euphoria, sedation, decreased reaction time and visual acuity, and lowered levels of alertness and behavioral control. Alcohol is broken down in the body at a rate of about 3.3 mmol/L (15 mg/dL) per hour.
Step-by-step explanation:
The immediate effect of alcohol depends on the drinker's blood alcohol concentration (BAC). BAC can be different for each person depending on their age, sex, pre-existing health condition, even if they drink the same amount of alcohol.
Acute alcohol administration results in a variety of changes to consciousness. At rather low doses, alcohol use is associated with feelings of euphoria. As the dose increases, people report feeling sedated. Generally, alcohol is associated with decreases in reaction time and visual acuity, lowered levels of alertness, and reduction in behavioral control.
Alcohol is broken down in the human body at a rate of about 3.3 mmol/L (15 mg/dL) per hour. Different BACs have different effects, but the effects of alcohol differ widely between individuals.
