The Association Between Recreational Cannabis Use and 24-hour Movement Behaviours: Perceptions of Youth Citizen Scientists.
Article in Journal of adolescence, 2025. 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
introductionThe prevalence of cannabis use among youth is rising globally, making it crucial to understand its role in health and well-being. While cannabis use is linked to various health outcomes, evidence on its relationship with 24-h movement behaviours (moderate-to-vigorous physical activity, sedentary behaviour, and sleep) in youth is limited. This study uses a digital citizen science approach to examine these associations among Canadian youth aged 13 to 21 years.
methodsAs a part of the Smart Platform, a digital citizen science initiative for ethical population health surveillance and policy interventions, this study engaged with 208 youth citizen scientists from Saskatchewan, Canada (August to December 2018). Participants used their smartphones to report moderate-to-vigorous physical activity, sedentary behaviour, sleep, substance use, mental health, and sociodemographic data over eight consecutive days. Linear regression models assessed associations between cannabis use and 24-h movement behaviours. Sedentary behaviour was further stratified into recreational screen time and other sedentary behaviour to explore distinct relationships with cannabis use.
resultsAfter adjusting for age, gender, parental education, and school, cannabis use was associated with higher hours/day of sedentary behaviour in the overall (β = 8.92, 95% CI = 1.11, 16.72; p-value = 0.02) and weekend models (β = 5.32, 95% CI = 0.89, 9.75; p-value = 0.02). Cannabis use was also associated with higher recreational screen time in both overall (β = 4.65, 95% CI = 0.19, 9.13; p-value = 0.04) and weekend models (β = 2.70, 95% CI = 0.08, 5.32; p-value = 0.04).
conclusionsThese findings need to be confirmed with longitudinal studies to develop holistic population health interventions focusing on policy solutions to address complex negative behaviours among youth.
