National Mental Health and Substance Use Protocol

Warning

This National Mental Health and Substance Use Protocol provides guidance for local interface documents and systems of care for people with co-occurring mental health and substance use conditions.

“The Scottish Government should ensure that each area has an agreed protocol in relation to the operational interfaces between mental health services and substance use services.” [Recommendation One from The Way Ahead: Rapid Review]

Discover more about the five components of the system, the ethos and approach required, along with resources and case studies to help you design your system of care.

NB. The version on this website is adapted to enable practitioners and professionals to consider questions in relation to the practical operation of their local systems of care. For the National Mental Health and Substance Use Protocol and other resources, visit the HIS Engage site
