Risk of Cannabis Use Disorder in Chronic Pain: Longitudinal Links to Pain Outcomes.
Article in Journal of addiction medicine. 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
objectivesThe aim of this study was to compare individuals with chronic pain who were cannabis nonusers and those at low, moderate, and high cannabis use disorder (CUD) risk levels on baseline psychosocial and pain-related characteristics, as well as the longitudinal trajectories of pain severity and interference.
methodsA cohort of 1453 individuals with chronic pain, recruited online, participated in this 2-year longitudinal study, which included baseline, 3-, 12-, and 24-month follow-up surveys. The Cannabis Abuse Screening Test was used to assess CUD risk, and the Brief Pain Inventory was used to assess pain outcomes.
resultsAmong participants (65.5% female; 86.1% White), 36.3% reported using cannabis, and 39.8% of cannabis users showed high CUD risk. Compared with nonusers, individuals at higher CUD risk tended to be younger, male, of lower socioeconomic status, and at higher risk of alcohol use disorder. They also reported greater pain severity and interference, more pronounced central sensitization symptoms, and elevated mental health symptoms. However, pain severity and interference trajectory slopes over 2 years were not different among the nonusers versus individuals at varying CUD risk levels.
conclusionsA significant portion of individuals with chronic pain who use cannabis may be at risk for CUD. Although higher CUD risk was not associated with worsening pain outcomes over 2 years compared to nonusers, its connection to worse mental health and pain symptoms at baseline highlights the need for targeted CUD risk assessments, patient education on CUD risk, and integrated care with mental health support in chronic pain management.
