Latent profile analysis of personality characteristics among US young adults in relation to cannabis use and intentions over time.
Article in Addictive behaviors, 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
objectivesYoung adults may use cannabis for distinct reasons, for example, related to their personalities or lifestyles. This study examined young adults' personality profiles and associations with cannabis use-related outcomes.
methodsUsing 3 waves of survey data (2023-2024) among 4,031 US young adults (M
resultsThree classes emerged: 1) the All-high-trait class (highest scores on all 5 personality characteristics; 21.1%); 2) the Moderate-extraversion/low-other-trait class (37.1%); and 3) the Low-extraversion/moderate-other-trait class (41.8%). At W1, past-month cannabis use was higher in the All-high-trait (52.2%) and Moderate-extraversion/low-other-trait classes vs. the Low-extraversion/moderate-other-trait class (43.3%). At W1, compared to the All-high-trait class, Low-extraversion/moderate-other-trait reported lower odds of use (aOR = 0.75, 95%CI = 0.63-0.90), and both Moderate-extraversion/low-other-trait and Low-extraversion/moderate-other-trait reported lower intentions (Moderate-extraversion/low-other-trait: B = -0.22, SE = 0.07; Low-extraversion/moderate-other-trait: B = -0.28, SE = 0.07). While odds of use and intentions generally decreased overall, class-by-time interactions indicated that: 1) odds of use decreased less from W1 to W2 in Low-extraversion/moderate-other-trait vs. Moderate-extraversion/low-other-trait (aOR = 1.23, 95%CI = 1.07-1.42); and 2) use intentions increased more from W1 to W2 in Moderate-extraversion/low-other-trait vs. All-high-trait (B = 0.18, SE = 0.09) and decreased less from W2 to W3 in Low-extraversion/moderate-other-trait vs. Moderate-extraversion/low-other-trait (B = 0.15, SE = 0.07).
conclusionsIntervention efforts should consider distinct personality profiles of young adults and potentially distinct mechanisms (e.g., social, emotional) underlying their cannabis use.
