Non-medical opioid (NMO) use in Canadian adolescents: Trends, risk factors, and regional variations.
Article in Canadian journal of public health = Revue canadienne de sante publique, 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
introductionNon-medical opioid (NMO) use is a serious issue among Canadian adolescents. Previous research has mainly focused on increases in opioid disorders and opioid-related mortality, while a focus on NMO use has been limited. Therefore, this study aims to examine how the reported NMO use changed over time among Canadian adolescents, focusing on three types of opioids: oxycodone, fentanyl, and other opioids (such as morphine, codeine, Tylenol #3). Additionally, this study will investigate demographic correlates of reported NMO use, including province of residence, age, Indigenous identity, sex, and urban/rural location.
methodsCanadian Student Tobacco, Alcohol, and Drugs Survey data (2014-2015, 2016-2017, 2018-2019, and 2021-2022) were used. Adjusted logistic regression analyses, accounting for changes in respondent demographics, were conducted.
resultsOverall adolescent reported past 12-month NMO use increased (2.5-3.2%) between 2014-2015 and 2021-2022. Specifically, past 12-month non-medical use of oxycodone (1.0-1.4%) and fentanyl (0.4-0.9%) increased over the study period, while use of other opioids declined slightly by 0.2% between 2018-2019 and 2021-2022. However, adjusted logistic regression analyses indicated that the odds of oxycodone use decreased between 2018-2019 and 2021-2022 (AOR = 0.88; 95% CI 0.86-0.90), whereas fentanyl use showed no significant change (AOR = 1.01; 95% CI 0.99-1.04). High school students, Indigenous-identifying, rural adolescents, and those in Alberta, Manitoba, and Quebec were particularly at higher odds.
conclusionThese findings call for continued efforts to regulate and prevent NMO use, especially among adolescents who are more likely to engage in such behaviours.
