Adrenochrome is a substance harvested from children's blood for a euphoric and life-enhancing benefit. It is mentioned in the Season Twenty-Four episode "South ParQ Vaccination Special".
Background[]
The conspiracy theory group QAnon believes in the existence of the Hollywood Elites, a secret cabal of Satan-worshipping, pedophilic cannibals. They had allegedly used Jeffrey Epstein's child sex services to obtain adrenochrome. The elites allegedly torture and kill the captive children and drink their blood. They depend on adrenochrome to maintain their positions of power and control the masses, and QAnon does everything they can to stop them.
