Cannabis use patterns, prevalence, and risk factors in Nigeria: a systematic review and meta-analysis.
Review in Journal of cannabis research, 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
backgroundReviews on cannabis use have been conducted in high-income countries, but limited data exist in Sub-Saharan Africa. In Nigeria, cannabis use is widespread, but systematic reviews summarizing the available data to generate robust evidence that can facilitate interventions have not been conducted. This systematic review and meta-analysis synthesized results from studies highlighting the patterns, prevalence, risk factors and motivations for cannabis use in Nigeria.
methodsDatabases searched include PubMed, Web of Science, Scopus, CINAHL, PsycINFO, ProQuest, African Journal Online (AJOL), and Google Scholar, for articles published in English between January 2000 and December 2023. Search terms were developed and slightly modified for each database. The primary outcomes were studies that examined the patterns, prevalence, risk factors, or motivation for cannabis use in Nigeria. The PECO framework guided the review, and all of the studies included were assessed for methodological rigor using the Joanna Briggs Institute checklist for prevalence studies.
resultsThe search yielded 1,911 research articles, which were screened, resulting in 72 studies being included in the review, with a total sample size of 45,968. Among adolescents, lifetime and past one-month prevalence of cannabis use were 3.90% (95% confidence interval (CI) = 1.99-7.51; I
conclusionCannabis use prevalence is high in Nigeria, and several factors that may increase cannabis related harm are the motivating factors. The findings show the need for prevention programs targeting young people and treatment services for problematic users.
