Mortality Risk Associated With Substance Use Disorder in South Korea: National Population-Based Study

This retrospective cohort study analyzed national health data from 2008-2022 in South Korea, finding that substance use disorder (SUD) patients had significantly higher mortality (16.8%) compared to non-SUD individuals (10.9%), with alcohol use disorder accounting for 89.7% of SUD-related deaths. Elevated mortality risk was particularly pronounced among lower-income individuals, those with disabilities, and those with psychiatric comorbidities, with increasing incidence rates observed in women and younger adults.
