Effective Early Intervention for Simple Drug Possession Offences: Evidence and Rationale for Diversion-Based Approaches

This briefing, authored by Jason Kew, presents an evidence-based rationale for implementing police-led diversion schemes as a more effective and humane response to simple drug possession offences. Drawing on UK and international research, the report critiques the ineffectiveness and harms of traditional criminal prosecution, particularly its disproportionate impact on marginalized communities. It advocates for early intervention models—such as community resolutions and educational pathways—that reduce reoffending, avoid unnecessary criminal records, and foster trust between law enforcement and communities. The document highlights the importance of trauma-informed, non-coercive responses that prioritize public health, social reintegration, and proportionality. The findings support operational reforms that empower frontline officers to utilize diversion consistently and equitably across all drug classifications, including Class A substances. This briefing contributes to ongoing efforts to align drug policy with human rights, social justice, and public health principles.
