The Global Policing Database is used to update a 2007 systematic review of the impact of street-level law enforcement interventions on drug crime and drug-related calls-for-service. A total of 26 studies (reported in 29 documents) were eligible for this updated review. Eighteen of the 26 studies reported sufficient data to calculate effect sizes.
We find that, overall, street-level policing approaches are effective in reducing drug crime, particularly those involving partnerships. We also find that geographically targeted law enforcement interventions are more effective in reducing drug crime than standard, unfocused approaches. Approaches that target larger problem areas for intervention are more effective for reducing drug crime (but not calls-for-service) than approaches that focus on micro problem places.
