Adverse outcomes following psychedelic use in adolescents and adults: associations with age and personality traits.
Article in Child and adolescent psychiatry and mental health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAdolescents are increasingly using classical psychedelics, yet little is known about how psychedelics use is related to their mental health. Emerging evidence suggests that adolescents may be more vulnerable to adverse outcomes in relation to psychedelic use compared to adults. This descriptive and exploratory study examined differences between adolescents and adults in reported psychedelic experiences, with a focus on adverse outcomes and the potential role of personality traits.
methodsData were drawn from a community sample (N = 1185), in which participants retrospectively reported on their most significant psychedelic experience and associations with adverse (e.g., confusion) and positive outcomes (e.g., meaningfulness). The sample was divided into adolescents aged 18–24 years and adults aged 25 years or older. Age groups were analysed both dichotomously (< 25 vs. ≥25 years) and continuously. Analyses of covariance (ANCOVA) and linear regressions were used to test the role of age and personality traits as predictors of adverse outcomes.
resultsAdolescents reported significantly more adverse outcomes compared to adults, including more negative personality change as well as more fearful experiences. Positive outcomes such as meaningfulness, mystical-type experiences, and improvements in relationships did not differ significantly between age groups. Age group remained a significant predictor of adverse outcomes after adjusting for personality traits. Neuroticism explained a substantially larger share of variance compared to age.
conclusionsThese findings suggest that while adolescents may derive similar positive effects from psychedelics as adults, they may be more vulnerable to adverse outcomes. The findings underscore the need for further longitudinal research to understand how developmental stages and individual differences influence psychedelic use outcomes.
