Summary
AI-generated from the abstractClassic 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.

Abstract
Preliminary evidence suggests that classic psychedelics may exert lasting positive effects on individuals' mood, cognition, and personality, but little is known about how these effects may differ across the lifespan. Emerging adulthood (18-29) is a critical developmental stage in which individuals transition from dependence on community institutions toward full independence. It is a time when psychedelic experimentation is common, and psychedelics could have distinctive psychological impacts during this phase, although the developmental significance of such effects remains largely untested. This integrative review offers a framework to generate hypotheses regarding possible ways that psychedelic use may positively interact with emerging adult development. Here, we review pathways by which classic psychedelics may facilitate emerging adults' positive orthogenetic, veridical-epistemic, eudaimonic, relational, and ethical developmental trajectories through changes in personality trait openness, belief systems, self-insight, and social concern. Finally, we offer future research directions and discuss key challenges for research into studying the developmental impact of classic psychedelic use in emerging adulthood.
