The word “blood” is used 447 times in the Authorized KJV Bible. Blood is never to be ingested.
Genesis 9:4 But flesh with the life thereof, which is the blood thereof, shall ye not eat.
Leviticus 7:26 Moreover ye shall eat no manner of blood, whether it be of fowl or of beast, in any of your dwellings.
Leviticus 17:11 For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.
Leviticus 19:26 ΒΆ Ye shall not eat any thing with the blood: neither shall ye use enchantment, nor observe times.
(Deuteronomy 12:23) “Only be sure that thou eat not the blood: for the blood is the life; and thou mayest not eat the life with the flesh.”

Vampirism is a form of Cannibalism, and sucks the very life out of one. The Bible says “The life is in the blood”. Ingestion of blood is forbidden by God.
Noteworthy: Cannibalism is addressed in the Bible, as well.
As for Adrenochrome, it is apparently a substance which is some sort of derivative of Adrenaline, obtained by causing a huge adrenaline dump by stress, pain, or torture, and then extracting the adrenalized blood by draining or killing the victim. Apparently, children are preferred over older humans.
The substance is then drunk or injected, apparently producing a state which is highly prized, sought after, and extremely expensive.
A heinous act, and set of acts.
Kidnapping, torture/rape, murder, child abuse, slavery, trafficking, and Witchcraft/Pharmakeia/Sorcery.
I don't know if there is any truth to the accusations of blood sacrifices. However, a leftist writer who uses the same snarky language used against conservatives on other topics would tend to induce belief in a conclusion opposite to his.
