Are there any religions besides Satanism, Santeria, and Christianity that have blood

Seriously. I'm curious.

Since when did Satanism have anything to do with blood drinking?

I'm seriously curious why you think that Christianity has blood drinking rituals... ??? If you are referring to the sacrament - drinking wine or more commonly grape juice - as a remembrance of Jesus's sacrifice and death that His Blood is said to cover sins - that does not mean that Christians drink blood.

Do people that drink bloody Mary's count as having a blood drinking ritual?!?

Satanism doesn't I'm sorry

A Wiccan and Proud
-Why?

and you forgot vampires which isn't a religion but blood drinking is involved...

Christianity has NOTHING to do with blood drinking. Catholics tend to have a blood-drinking issue, but then again the Vatican really isn't a Christian organization, now is it?

Christians DO NOT actually drink blood. Only drink grape juice [or wine] in the ritual of the Last Supper. The others MAY drink real blood, as far as I know. I hope not.

EXCUSE ME? Blood drinking and Christianity? What have YOU been drinking?

I watched a program on Discovery about Vampires . . or people who believe they are vampires and they drink blood . .

Vampire cults also...Christianity doesn't actually have a "blood" drinking ritual, unless you actually believe in it, and then during communion the wine becomes symbolic blood, as opposed to the others, which use blood as blood.
Also, the old Aztec religions drank blood, and did other even more unsettling things, no propaganda there, some of their festivals would turn into real literal blood baths.
That's off the top of my head.

Hail Eris! All Hail Discordia!

Daemonolatry has a mostly abandoned ritual where drops of blood from each participant in the rite was placed in a chalice of wine and drank by everyone. But that practice was abandoned when AIDS showed up and people started to learn more about blood born disease.

Also - Satanism doesn't have any blood drinking rituals unless you count the Demonolators who are also pantheistic Satanists, but like I said the Demonolatry blood drinking ritual has been abandoned.
