Drug Use Patterns and Characteristics by Drug Type Among Drug Abusers: Findings From the Survey of Drug Abusers in Korea 2021.
Article in Journal of Korean medical science, 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
backgroundAlthough substance use disorders are increasingly recognized in the Republic of Korea (South Korea), empirical data on the prevalence and characteristics of drug use among treatment-seeking populations remain limited. This study examined the rate and temporal patterns of major psychoactive substance use-specifically sedatives/hypnotics/tranquilizers (sedatives), amphetamines, and marijuana/cannabis (cannabis)-across three timeframes and explored the associated sociodemographic and clinical factors.
methodsData were obtained from 540 adults with a history of substance use, recruited from medical and rehabilitation institutions as part of the 2021 Survey of Drug Abusers in Korea. Sociodemographic and clinical factors-including Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5)-based substance use disorder (SUD) diagnosis, self-recognition of addiction, depression, anxiety, and Addiction Severity Index (ASI) scores-were assessed. Group comparisons were conducted using χ² and
resultsAmong the 540 individuals with a history of substance use, the lifetime rate of use was highest for amphetamines (71.9%), followed by cannabis (52.8%) and sedatives (38.1%). Sedative use remained relatively consistent across timeframes (30-day: 21.9%; 1-year: 28.9%; lifetime: 38.1%), suggesting patterns of chronic or concurrent use. Across all three substance groups, participants exhibited poorer mental health, including elevated levels of depression, anxiety, or psychiatric severity. Amphetamine and sedative users were more likely to be female, older, and of lower socioeconomic and educational status, with greater impairment in psychiatric, family, and social functioning, as well as higher self-recognition of addiction. In contrast, cannabis users were predominantly younger males with higher socioeconomic status but elevated anxiety levels. Institutional affiliation also differed by substance type: cannabis users were more frequently associated with rehabilitation centers, whereas amphetamine users were more often treated in medical institutions.
conclusionFindings highlight the coexistence of shared psychosocial vulnerabilities and substance-specific risk profiles in Korea. Integrated, multidimensional interventions-linking psychiatric care, social support, and economic protection-are needed for amphetamine and sedative users. For younger cannabis users, early intervention and relapse prevention are essential. Strengthening coordination between medical and rehabilitation systems under Korea's Judicial-Treatment-Rehabilitation Linkage Model may reduce stigma and enhance recovery-oriented care for individuals with SUD.
