xkcd Figures Out If You Can Get Drunk by Drinking the Blood of a Drunk Person

In the latest edition of “What If” by xkcd, Randall Munroe addresses a reader who asks if it’s possible to get drunk by drinking the blood of someone who has had a lot to drink. The answer to the somewhat graphic question is “no.”

You wouldn’t throw up because because of the alcohol; you’d just throw up because you’re drinking blood. If you somehow avoided vomiting, you would have ingested a total of 2 grams of ethanol, which is the amount you’d get from one shot glass full of beer.
