Naloxone is a crucial part of efforts to tackle Scotland’s drug-related death public health emergency as it can reverse effects of an opioid-related overdose for long enough for professional medical intervention and thus save someone’s life. Supply of naloxone has increased across Scotland and peer supply programmes are proving to be particularly effective at reaching target populations. To build on previous work, Scottish Drugs Forum (SDF) sought to maximise peer to peer naloxone supply with a coordinated and supported approach by delivering high quality training to peers who have experience of substance use, providing ongoing support, and developing a national peer network to enhance the delivery of naloxone provision by people who have experience of drug use. This project was funded by the Scottish Drug Deaths Taskforce Innovation Fund. This evaluation aims to explore the peer-to-peer naloxone programme within three pilot areas (one prison, one rural, one urban) and will focus on novel approaches in this programme compared to previous service provision, including effects of paying peers and exploration of local challenges.
