BACKGROUND: Chronic substance use (CSU) is associated with health problems, including self-harm, placing a significant burden on health care resources and emergency departments (EDs). This is problematic in low- and middle-income countries like South Africa (SA), where primary care facilitates and emergency departments (EDs) are often poorly resourced AIM: To investigate the epidemiology of CSU and self-harm and to consider the implications for primary health care service delivery and suicide prevention in SA METHODS: Data were collected from 238 consecutive self-harm patients treated at the emergency department (ED) of an urban hospital in SA. The data were analysed using bivariate and multivariate analyses RESULTS: Approximately 37% of self-harm patients reported CSU. The patients in the CSU subgroup, compared to other self-harm patients, were more likely to be men (odds ratio [OR] = 8.33, 95% confidence interval [CI] = 3.19-20.9, p < 0.001), to have self-harmed by inflicting damage to their body tissue OR = 4.45, 95% CI = 1.77-11.2, p < 0.01) and to have a history of self-harm (OR = 3.71, 95% CI = 1.44-9.54, p = 0.007). A significantly smaller proportion of CSU patients, compared to other self-harm patients, were referred for psychiatric assessment (OR = 8.05, 95% CI = 4.16-15.7, p < 0.001 CONCLUSION: The findings of this study confirm that CSU is associated with greater service utilisation and repetition of self-harm among patients in primary health care settings. Treating self-harm as the presenting problem within primary care settings does not necessarily ensure that patients receive the care that they need. It might be helpful to include psychiatric assessments and screening for CSU as an integral component of care for self-harm patients who present in primary health care settings
