Medical cannabis utilization in children - a study based on a nationwide cohort.
Article in Frontiers in pharmacology, 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
Introduction: This study aimed to evaluate the utilization of medical cannabis in a pediatric population and compare short-term persistence rates with those in adolescents and young adults. Methods: In this retrospective, nationwide cohort study supplemented by data from an open-label study of children with ASD, patient cases under 12 years of age who received medical cannabis treatment between 2018 and 2022 were analyzed. The primary outcome assessed was treatment persistence within the first 3 months. Secondary outcomes included changes in THC ratios, amounts dispensed, and reasons for treatment discontinuation. Results: The patient population consisted of 1,341 children using medical cannabis for ASD (751), epilepsy (330), Tourette syndrome (165), and pediatric cancer (95). Out of 3,007 consecutive medical cannabis sessions, the adjusted hazard ratio for discontinuation in the first 3 months was 0.83 (95% CI [0.71-0.96], p = 0.01) for young adults compared to children. Approximately 60%-70% of children discontinued therapy within the first 6 months. Significant alterations in THC ratios or dispensed amounts were observed in most sessions within the initial 6 months. In the open-label study dataset, most treatment discontinuations were primarily attributed to adverse effects and a perceived lack of therapeutic efficacy. Conclusion: Our findings suggest that short-term persistence of medical cannabis therapy is lower in children compared to adolescents and young adults. Moreover, many pediatric patients required adjustments to their THC ratios and showed a high frequency of treatment discontinuation. These observations underscore the importance of targeted strategies to improve medical cannabis treatment effectiveness and adherence in the pediatric population. Although MC may offer therapeutic benefits for pediatric patients, our findings emphasize the importance of careful patient selection and close medical follow-up to optimize clinical outcomes.
