U.S. Justice Studies Cocaine Law Enforcement Relaxation Policy

Nov 4, 2020 | Cases, Health Policy

A system dynamics model reproduces a variety of national indicator data reflecting cocaine use and supply over a 15-year period and provides detailed estimates of actual underlying prevalence. Sensitivity testing clarifies the source of observed trends.  Alternative scenarios with possible policy implications were simulated and projected.

In one analysis, the model was applied to determine the potential impact of policies involving a relaxation of law enforcement.  The model suggests that a policy that eliminates both drug seizures and retail-level arrests would reduce the criminal justice load, but could lead to a large increase in cocaine use and addiction.
