Fentanyl overdoses cluster geographically more than non-fentanyl overdoses, according to a study just released by Columbia University Mailman School of Public Health. The findings suggest that fentanyl-involved overdoses are concentrated in resource deprived neighborhoods over and above what data show for opioid and polydrug overdoses. This is one of few studies to examine the local geographic distribution of drug overdoses and associated neighborhood-level risk factors. The results are published online in the American Journal of Public Health.
