Many states have responded to the national opioid epidemic by limiting how many pain pills doctors can prescribe, contributing to the decline in opioid prescriptions filled at pharmacies across the country. But a new Penn study suggests that to truly tackle the opioid epidemic, states may need a more granular approach. The study, led by M. Kit Delgado, MD, an assistant professor of Emergency Medicine, found that opioid prescribing for minor injuries remains high and varies widely by state.
