The Kush Drug Epidemic in Sierra Leone: Public Health Implications, Socioeconomic Drivers and Health System Responses.
Review in Public health challenges, 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
Background: Kush, a synthetic drug combining cannabinoids and nitazene opioids, has emerged as a major public health concern in Sierra Leone, with reported prevalence and clinical severity increasing markedly as it was first identified. This review examines the health consequences of Kush use, the socioeconomic and structural drivers underpinning its spread, and the adequacy of health system and policy responses across the Mano River Basin. Methods: A narrative review was conducted using structured searches of PubMed/MEDLINE, Scopus, Web of Science and Google Scholar (2016-2025). Grey literature, including government policy documents, reports from international organisations, civil society publications and credible media sources, was systematically reviewed. Eligible sources addressed Kush or related synthetic drug use in Sierra Leone and the wider West African subregion, with emphasis on health outcomes, socioeconomic determinants, health system capacity and policy responses. Results: Kush exhibits unpredictable toxicity and high dependence potential, with documented associations including acute psychosis, cognitive impairment, severe morbidity and rising mortality. Weak surveillance systems likely underestimate its burden. Structural drivers include entrenched youth unemployment, poverty, rapid urbanisation, post-conflict trauma and limited access to education and mental health services. Regional dynamics across Sierra Leone, Liberia, Guinea and The Gambia reinforce its transnational spread. Responses since 2024 have intensified but remain disproportionately focused on law enforcement, whereas prevention, treatment and workforce development remain critically under-resourced. Conclusion: The Kush crisis exemplifies a complex, cross-border public health emergency. Addressing it requires integrated, evidence-informed strategies that strengthen health systems, expand community-based interventions, improve toxicological surveillance and enhance regional coordination under ECOWAS frameworks.
