In the U.S., one drink is 14 g of pure alcohol—often 12 oz beer (5% ABV), 5 oz wine (12%), or 1.5 oz 80-proof spirits.

Alcohol is “bad for your liver” once drinking is frequent or heavy enough to drive fat buildup, inflammation, or scarring in the liver.

Alcohol starts raising health risk as intake rises; staying at or under standard low-risk limits lowers harm for most adults.

The stomach absorbs about 20% of alcohol, with most absorption in the small intestine and shaped by food and timing.

Most DayQuil cold and flu products contain 0% alcohol, though a few specialty liquids list about 10% alcohol by volume on the label today.

An 8% ABV drink is 8% pure alcohol by volume, so 100 mL of it contains 8 mL of ethanol.

Most white wine sits near 11–13% ABV, with lighter sweet styles lower and fortified bottles higher.

Drink-driving limits vary by place; in many areas the legal cap for most drivers is 0.08 g/dL BAC or lower.

80 proof liquor is 40% alcohol by volume (ABV), so 100 mL of it holds 40 mL of pure alcohol.

A 5% ABV drink contains 5 mL of pure alcohol per 100 mL, so a 12-oz serving holds about 0.6 oz of alcohol.
