Understanding and preventing drug-related interpersonal violence in Ireland through a public health approach

• Drug-related violence should be conceptualised and responded to from a public health perspective. • The typology and ecological model of violence can be directly mapped onto a public health framework. • Utilising a public health approach can directly address the current challenges surrounding the discourse on security and preparedness. • By adopting this approach with an established evidence base and engaging the transdisciplinary community, a new model for policy and practice development for drug related violence can be implemented. There is an unresolved tension between the growing emphasis on public health approaches to illicit drug use and to interpersonal violence in some quarters, and the common refrain that drug-related violence is best resolved through law enforcement and criminalisation in others. It is timely, therefore, to analyse these concepts together and through an interdisciplinary lens, exploring how we conceptualise and prevent illicit drug-related interpersonal violence from a public health perspective. This essay explores public health approaches to preventing illicit drug-related interpersonal violence. We situate our analysis in Ireland, where our work is primarily based, and where we feel there is some potential to drive forward public health approaches. We start by outlining some key messages from the empirical literature on the dynamics of illicit drug-related interpersonal violence in Ireland. Next, we seek to map the typology of violence and the World Health Organisation (WHO) ecological model of violence onto evidence-informed approaches to prevention from public health. Finally, we identify some of the approaches which could help Ireland reimagine efforts to prevent at least some forms of drug-related interpersonal violence, while avoiding the harms of criminalisation.
