This article aims to identify the main impacts of drug law enforcement on policing. It points to five interrelated effects:

1. Suppression focused on minor offenses and the weakest links in the chain;
2. Arrest patterns often based on stereotypes that affect the most vulnerable populations;
3. Perverse incentives that reward indiscriminate repression;
4. Corruption and penetration of organized crime; and
5. Excessive use of force and violations of human rights.

Rather than discuss causes and effects, this study identifies drug policy as a factor that aggravates policing problems. Based on its findings, it pinpoints a series of interventions designed to keep low-level offenders out of the judicial system, explaining the advantages and challenges of each intervention. The article states that while this set of measures would have limited effects in terms of addressing structural problems in police institutions, it has the potential to focus limited state resources, curb levels of discretion, and implement differentiated interventions for the various links in the drug chain. As an immediate step, it recommends adopting alternatives to arrest and incarceration for those at the bottom of the chain, as a way to change incentives within the police force and redirect its objectives and metrics.
