▼ A recent study inspired headlines and tweetsthe likes of “drinking young people’s blood could help you live longer and prevent age-related diseases.” We atPopular Sciencewould rather you not do that. Here are several arguments against drinking human blood.
Drinking human blood can make you very sick
For starters, a lot of blood you’ll encounter on the street carries some kind of pathogen. Drinking infected blood is a great way to get your very own infection. And unlike animals who’ve evolved to live on blood, humans can actually  wind up with iron overdoses if  they overindulge.
There are people feel compelled to drink the blood of others, and even follow rules to make sure they’re  doing it safely and consensually. Some of the people who do this feel they have a genuine medical condition that is improved through the drinking of blood, but it’s important that you discuss these symptoms and feelings with your physician. And you definitely shouldn’t just take a shot of the first blood you’re offered.
Research is sorely needed to determine whether clinical vampires suffer from a medical ailment, psychosomatic symptoms, mental illness, or some combination of the three. Many say that they would happily switch to  more socially acceptable  supplementsif they worked as well.
Side note: don’t inject human blood, either
A couple of years ago, police in Bucks County, PA picked up a man  carrying a vial of red liquid. It turned out to contain the blood of someone who’d taken fentanyl—meant for later injection into the veins of another drug user. Its street name? BLOOD. Don’t do BLOOD, kids.
There are so many other bloods to consume! (▪ ▪ ▪)
