The impact of a police crackdown on a street drug scene: Evidence from the street

This article documents the impact of a police crackdown on a street heroin market in a suburb of Melbourne, Australia, as perceived by individuals involved in the market. While our data suggest that 'Operation Clean Heart' achieved its objective of reducing the visible aspects of this street drug scene, they also imply that the drug market rapidly adapted to its new conditions and that the impact of the operation was essentially superficial and temporary. In addition, we contend that the operation had numerous (unintended) negative consequences, some of which are potentially harmful to public health. Negative outcomes implied by our data included the partial displacement of the drug scene to nearby metropolitan areas; the discouragement of safe injecting practice and safe needle and syringe disposal; and more frequent occurrences of violence and fraud. These outcomes may outweigh the perceived positive impacts, which were achieved at significant public expense. We conclude that police crackdowns are inappropriate responses to illicit drug problems; instead, in line with longstanding Australian policy, approaches which incorporate and balance demand reduction, supply reduction and harm reduction principles should be followed.
