This is a report from the CDC that shows the increase of syringe service programs (SSP) offering overdose education and naloxone education (OEND) over time. 94% of SSPs were offering OEND in 2019, up from 55% in 2013. However, there is geographic variation, with southeastern states and middle Atlantic states still lagging behind despite high overdose death rates.
