Objectives: Evaluate the relationship between the opioid epidemic and homicide rates in the United States. Methods: A county-level cross-sectional analysis covering the period 1999 to 2015. The race-specific homicide rate and the race-specific opioid-related overdose death rate are regressed on demographic, social, and economic covariates. Results: The race-specific opioid-related overdose death rate is positively associated with race-specific homicide rates, net of controls. The results are generally robust across alternative samples and model specifications. Conclusions: We interpret the results as reflecting the violent dynamics of street drug markets, although more research is needed to draw definitive conclusions about the mechanisms linking opioid demand and homicide.
