The Sonoran desert toad (Bufo alvarius), not the marine toad (Bufo marinus), is a plausible candidate for ritual use by ancient Mesoamericans. The marine toad's venom is too toxic for such use, but the Sonoran desert toad secretes large amounts of the potent hallucinogen 5-MeO-DMT. Experiments show that while the venom is toxic if eaten, it can be safely smoked and is powerfully psychoactive by that route. This is the first documented hallucinogenic agent from the animal kingdom and provides clear evidence of a psychoactive toad that could have been employed by Precolumbian peoples.
Psychiatric models that focus on isolated biological dysfunction fail to capture the complexity and context dependence of mental disorders. Drawing on neuroscience, complexity science, and psychedelic research, this paper proposes a systems-based framework where therapeutic change involves a phased process of perturbation, reorganization, and consolidation. Interventions modulate system stability and plasticity, with outcomes shaped by biological, psychological, relational, and environmental factors. Psychedelic-assisted therapies exemplify this by transiently destabilizing entrenched patterns, increasing flexibility, and enabling reorganization under supportive conditions. Recovery is reframed as increased coherence, flexibility, and adaptive capacity rather than mere symptom reduction. This perspective calls for longitudinal, context-sensitive outcome measures and hybrid methodologies.
