Harm Reduction International developed tools for assessing national harm reduction investment and spending on drug law enforcement. This report presents the research findings generated by these tools in seven Asian countries. It provides insights on the state of harm reduction financing, informed by donor and government stakeholders, civil society and community representatives. It outlines evidence that can be used to inform advocacy for increased domestic and donor support for harm reduction, covering factors that underpin sustainability and those that pose challenges. It also  explores spending on drug law enforcement in two countries, which can be used to inform  advocacy for rebalancing drug policy investments towards health and harm reduction.
