TL;DR

  • Hard evidence on every inhabited continent. Lab-confirmed peyote (TX 3700 BCE), ayahuasca kit (Bolivia 1000 CE), high-THC cannabis (Xinjiang 2500 BCE), ergotized kykeon (Greece 4th c BCE), etc.
  • Iconography fills gaps. Tassili “mushroom shaman,” Selva Pascuala psilocybes, Moche San Pedro cactus, Viking henbane berserkers.
  • Animal & venom highs aren’t fringe: Sonoran toad 5-MeO-DMT, Indian cobra venom trance.
  • Shared pharmacology. Most act via 5-HT₂A (tryptamines/phenethylamines) or anticholinergic/tropane or κ-opioid channels—explaining convergent serpent-vine-rebirth motifs.
  • Biggest blind spots: Sub-Saharan Africa outside Gabon; residue work on European “witches’ ointments”; Oceania pre-Lapita pituri.
  • Next steps: residue metabolomics, ancient DNA of fungi, ML rock-art scans, isotopic sourcing of trade.

Continental Evidence Overview

North America#

  • Peyote, Lower Pecos TX (3700 – 1000 BCE). Mescaline in 31 coprolites & desiccated buttons—score 5.1
  • Psilocybe “mushroom stones,” Maya (≥1000 BCE). Carved cap-headed effigies with sacrificial altars—3.
  • Sonoran Desert toad (Bufo alvarius) venom (5-MeO-DMT) inhaled by Seri / Yaqui—2.
  • Mazatec Salvia divinorum diterpene salvinorin-A documented 1950s; curing chants echo colonial reports—4.
  • Sacred Datura wrightii quids w/ scopolamine in Chumash cave—5.

South America#

  • Ayahuasca pharmacopoeia, Andes (1000 CE). Shaman’s fox-snout pouch held harmine, DMT, coca, Anadenanthera—5.2
  • San Pedro cactus on Moche ceramics (200 BCE – 800 CE). Fanged deities clutch ribbed cactus—3.
  • Vilca/yopo snuffs, Inca Cueva (3000 – 2000 BCE). Pipes test positive for bufotenine—4.

Europe#

  • Ergotized kykeon, sanctuary vessel (4th c BCE). Ergopeptine residues match Claviceps purpurea—4.3
  • Selva Pascuala mural, Spain (~6000 BCE). Thirteen gilled caps beside a bull, likely Psilocybe hispanica—3.4
  • Sámi Amanita muscaria solstice rites (ethnographic)—2.
  • **Henbane seeds in Viking graves (9-11 C CE); saga fury aligns with scopolamine—2.

Africa#

  • Bwiti Tabernanthe iboga (19 C – present). Alkaloid ibogaine isolated 1901; colonial diaries describe “skin-shedding vision quest”—4.5
  • Tassili n’Ajjer “mushroom shaman” (~7000 BCE). Therianthrope waving cap-like objects—3.6
  • **Blue lotus (Nymphaea caerulea) petals in New Kingdom tombs; aporphine-rich extracts sedated banquet guests—4.7
  • **Khat (Catha edulis) Sufi zikr (12 C – present)—2.

Asia#

  • Soma/Haoma presses, Bactria-Margiana (2000 BCE). Stone filters with Ephedra twigs—3.8
  • High-THC cannabis in Yanghai Tomb #90 (Xinjiang 2500 BCE). Thirteen whole plants, 2.5 % THC—4.9
  • **Koryak Amanita urine-recycling loop (Siberia)—2.
  • Snake-venom trance (modern India). Case reports show κ-opioid activation; folk antecedents likely older—2.10

Oceania#

  • Kava (Piper methysticum) clone trail (≥3000 BCE). Lapita diaspora linguistics + phytoliths at Teouma, Vanuatu—4.11
  • Pituri (Duboisia hopwoodii) stimulant-hallucinogen mix. Historic journals: “Aboriginal telepathy” during rituals; nicotine + scopoletin—3.12
  • Acacia DMT smoke (speculative). Ethnobotanical hints but no residue yet—1.13
  • Karaka berry tox brew (Māori). Neurotoxic drupes processed for ritual—1.

Shared Pharmacology: How the Molecules Converge#

PathwayRepresentative AgentsTypical Vision Motifs
5-HT₂A agonismPsilocybin, DMT, mescaline, LSDSerpents, kaleidoscopic tunnels, ego-dissolution
Anticholinergic tropane blockadeHenbane, mandrake, brugmansiaFlight, lycanthropy, blackout amnesia
κ-Opioid agonismSalvinorin-A, cobra venom peptidesFractal folding, dysphoria → transcendence
β-Carboline MAOI potentiationHarmine/harmaline in ayahuascaAmplifies DMT & tryptamine visions
Nicotine-scopoline synergyPituri quidHyper-vigilance, time dilation

The convergent serpent-vine-womb symbolism likely tracks the 5-HT₂A “coiling” closed-eye geometric set and the emetic/rebirth physiology of β-carbolines.

FAQ#

Q 1. What is the oldest laboratory-confirmed entheogen?
A. Radiocarbon-dated peyote buttons (mescaline positive) from Lower Pecos, Texas, place confirmed ritual use at least 3700 BCE, the earliest chemically verified psychoactive on record.1

Q 2. Which continent has the weakest archaeological trail?
A. Oceania: kava is well attested, but pituri and putative Acacia-DMT rites still lack residue-grade confirmation, leaving large temporal gaps.

Q 3. Did ancient Europeans really drink an LSD-like brew at Eleusis?
A. A 2023 ergoline LC-MS study of a 4th-century BCE chalice from a temple near Eleusis detected Claviceps alkaloids, lending hard support to the ergotized-kykeon hypothesis.3

Q 4. Are animal entheogens common?
A. More than you’d guess: Sonoran toad (5-MeO-DMT), Amazonian Phyllomedusa frog-skin “kambô,” and experimental cobra-venom trances all show that vertebrate toxins also fuel visionary states.

Q 5. What research could clinch the disputed cases?
A. Ultra-high-resolution residue metabolomics on “witches’ ointment” pots and isotopic mapping of pituri gourds could convert speculative traditions into lab-confirmed data within a decade.
