Prevalence of Self-Reported Adverse Effects to Cannabis by Older Canadians: A Cross-Sectional Analysis.
Article in Drugs & aging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectiveDespite the increasing use of cannabis by older Canadians, little is known about cannabis safety in this population, particularly in non-clinical settings. The purpose of this study was to describe the self-reported adverse effects experienced by community-dwelling older Canadians who use cannabis.
methodsCanadians aged 50 years and older completed an online survey regarding their knowledge, perceptions, and experiences with cannabis. Respondents who reported current cannabis use were asked to report any adverse effects experienced in the past year related to their cannabis use. Adverse effects were categorized, and multivariate logistic regressions were performed to assess predictors of adverse effects.
resultsA total of 1615 older adults completed the survey, of whom 503 reported current use of cannabis and were included in this analysis. Adverse effects were reported by 308 participants (61.2%) and included dry mouth (36.2%), feeling high (25.9%), and adverse effects impacting balance (22.1%) and mental alertness (20.3%). Compared with participants aged 50-60 years, those aged 70 years and older had lower odds of reporting any adverse effects (odds ratio (OR) 0.524, 95% confidence interval (CI) 0.303-0.906) or adverse effects impacting mental alertness (OR 0.318, 95% CI 0.172-0.588). Female participants had higher odds of reporting any adverse effect (OR 1.989, 95% CI 1.332-2971) or adverse effects impacting balance (OR 1.930, 95% CI 1.198-3.109).
conclusionsAdverse effects to cannabis are common amongst community-dwelling older adults. Increased education and guidance regarding adverse effects of cannabis, including the composition and dose of cannabis products, may help increase safe use by this population.
