What is the effect of drinking alcohol on the blood alcohol level?

• For an average sized person, each of the following will raise the blood alcohol level approximately 25 mg/dL: 1 oz (one shot) of alcohol, 4 oz (half cup) of wine, or 12 oz (one can) of beer.
• And an average adult will break-down (metabolize) alcohol at a rate of 15-25 mg/dL per hour.
• Example: Drinking 3-4 beers will raise your alcohol level from 0 to 100 mg/dL and it will take 4-7 hours before your alcohol level is back to zero.
