Brain Behav November 1, 2025 Jake Payne, Oliver Robinson, Kevin O. St. Arnaud et al. 3 citations
Classic psychedelics may produce lasting positive effects on mood, cognition, and personality, but how these effects vary by age is unclear. Emerging adulthood (ages 18-29) is a critical developmental period marked by transition to independence and common psychedelic experimentation. This integrative review proposes a framework for how psychedelic use could positively influence development during this stage, including changes in personality trait openness, belief systems, self-insight, and social concern. The authors outline pathways for orthogenetic, veridical-epistemic, eudaimonic, relational, and ethical developmental trajectories. They also identify future research directions and key challenges for studying psychedelics' developmental impact in emerging adulthood.
