The thesis that entheogens shaped Abrahamic origins did not end with Allegro's discrediting; it returned in more empirically grounded, though still contested, forms across Christian and Israelite material alike. Brian Muraresku's 2020 book The Immortality Key argues for continuity between the psychoactive kykeon of the Eleusinian Mysteries, the subject of Wasson, Hofmann and Ruck's earlier The Road to Eleusis, and wine used in early Christian communities, proposing that some early Eucharistic wine may have been deliberately spiked, possibly with ergot alkaloids. Muraresku leans on genuine archaeochemical residue evidence rather than Allegro's speculative philology, which is why classicists take it more seriously, though critics note the strongest residue evidence predates and lies outside any Christian context.
A separate hypothesis addresses the Hebrew Bible directly: the cognitive scientist Benny Shanon, a researcher of ayahuasca phenomenology, proposed in a 2008 paper that Moses' burning bush and Sinai revelations could reflect an entheogenic experience from acacia paired with Syrian rue, a combination structurally similar to ayahuasca, a hypothesis Shanon himself labeled speculative in the paper's own title.
Critics note the absence of textual or archaeological evidence for such a preparation at Sinai, that smoke from burning acacia wood alone is not considered a credible route to the compound the theory requires, which is why Shanon's mechanism needed the additional oral rue pairing, and that the psychoactive content of the acacia native to the Sinai region is itself disputed. This atlas records both as live, published and debated positions, distinct in evidentiary standing from Allegro's thesis, which the field treats as settled and rejected.
