Count Your Drinks, Not Your Cups
When drinking alcohol, people often mistakenly base the quantity of alcohol consumed on the number of cups they drank. This can lead to over consumption of alcohol. Students who choose to drink alcohol should consider the type and amount of alcohol inside their cup. They can use the lines in a red cup (like the one to the left) to help them keep track of the quantity of alcohol they are drinking. The bottom line can be used as a marker for one drink of hard liquor. The second line can be used to measure one drink of wine. The third line can be used to measure one drink of beer. On average, it takes the body approximately one to two hours to eliminate the alcohol in one drink.
What is a Drink?
- 12 ounces = one drink
- 16 ounces = 1.3 drinks
- 22 ounces = two drinks
- 40 ounces = 3.3 drinks
- 12 ounces = one and a half drinks
- 16 ounces = two drinks
- 22 ounces = two and a half drinks
- 40 ounces = four and a half drinks
- 5 ounces = one drink
- 750 mL (25 ounce) bottle = five drinks
- a mixed drink = one or more drinks*
- a pint (16 ounces) = 11 drinks
- a fifth (25 ounces) = 17 drinks
- 1.75 L (59 ounces) = 39 drinks
*Depending on factors such as the type of spirits and the recipe, one mixed drink can contain from one to three or more standard drinks.
Blood alcohol content or concentration (BAC), is the concentration of alcohol in blood. BAC measures the amount of alcohol that is absorbed by the bloodstream. A standard drink will raise a person’s BAC an average of .02 percent. The rate of alcohol concentration in the bloodstream is influenced by a wide range of factors:
- Type and number of drinks: See What is a Drink? above.
- Time: On average, it takes the body approximately one to two hours to eliminate the alcohol in one drink.
- Body weight and composition: Heavier individuals tend to have more body mass and therefore more blood to diffuse alcohol in their BAC.
- Gender: Women tend to have more body fat and less body fluid. As a result, they will often experience a higher BAC when drinking the same amount of alcohol as a male.
- Food: The amount of food in the stomach impacts how quickly alcohol is absorbed into the bloodstream. Food will not change the amount of alcohol that enters the bloodstream, but it will slow down the rate of absorption.
To calculate BAC, use the BAC calculator.
P.U.B.S. Signs of Alcohol Poisoning
Use P.U.B.S. as a guide to the symptoms of alcohol overdose:
- Puking while passed out.
- Unresponsive to stimulation (pinch or shaking)
- Breathing (slow, shallow or no breathing)
- Skin (blue, cold or clammy)
Students who are not sure whether or not to call for help should use P.U.B.S. Student who see even one sign of alcohol overdose should call 911.
