A pilot of a whole system approach to tackling gambling harm in Glasgow took place between 2022 and 2023. A systems map was created through stakeholder engagement in support of this work; discussions with lived experience, academia, public and third sectors were undertaken in its development. Its purpose is to illustrate the complexity of the local system and how many factors touch on gambling harm. It is a historic document that may be of interest as other local areas seek to address gambling harm.
