Unpredictable Behavior Under the Influence of “Magic Mushrooms”: A Case Report and Review of the Literature

Journal of Forensic Sciences December 12, 2018 Emma Honyiglo, Angélique Franchi, Nathalie Cartiser et al. 33 citations

A young man without psychiatric history died after jumping from a second-story balcony while under the influence of psilocybin mushrooms. Psilocin concentrations measured 60 ng/mL in peripheral blood, 67 ng/mL in cardiac blood, 2230 ng/mL in urine, 3102 ng/mL in bile, and 57 ng/mL in vitreous humor. The case and literature review demonstrate that even regular users in seemingly safe circumstances can suffer fatal outcomes from psilocybin mushrooms alone.

Identification of 5-hydroxy-tryptamine (bufotenine) in takini (Brosimumacutifolium Huber subsp. acutifolium C.C. Berg, Moraceae), a shamanic potion used in the Guiana Plateau.

Journal of ethnopharmacology June 30, 2006 Christian Moretti, Yvan Gaillard, Pierre Grenand et al. 32 citations

The hallucinogenic potion takini, used by shamans in Suriname, French Guiana, and eastern Brazil, comes from the latex of the Brosimum acutifolium tree. Chemical and botanical analysis reveals that its active ingredient is bufotenine, a psychoactive compound. This compound occurs only in the subspecies Brosimum acutifolium Huber subsp. acutifolium C.C. Berg, which grows in the eastern Guianas. The finding explains why the tree's psychotropic properties seemed inconsistent with its broader medicinal uses in surrounding regions.

Intoxication mortelle à l’iboga: quantification de l’ibogaïne et de l’ibogamine dans des racines d’ibogaet dans des prélèvementspost-mortempar CPG-SM/SM

Annales de Toxicologie Analytique January 1, 2012 Cédric Mazoyer, Jérémy Carlier, Michel Péoc’h et al. 2 citations

A 27-year-old man with a history of drug addiction died about twelve hours after ingesting powdered iboga root during a detoxification program. The main alkaloids ibogaine and ibogamine were measured in the powder and in biological fluids collected at the scene and during autopsy. Concentrations in peripheral blood taken at the scene, peripheral blood from autopsy, urine, and gastric fluid ranged from 0.65 to 53.5 µg/mL for ibogaine and 0.05 to 4.34 µg/mL for ibogamine. The powder contained 7.2% ibogaine and 0.6% ibogamine. Additional toxicological tests revealed concurrent use of diazepam and methadone, supporting the conclusion that death resulted from a mixed overdose with ibogaine as the primary toxic agent.
