Description

Redirection programs based on community-based interventions aim to divert offenders who use Class A drugs (crack, ecstasy, heroin, LSD) from the criminal justice system by suspending the prosecution process in exchange for the (voluntary or mandatory) participation of said individuals in substance abuse treatment programs.
These interventions are based on the interpretation that the crimes committed by those individuals are, to a large extent, conditioned by their search for funds to finance their drug abuse. Therefore, the main objective of these programs, in addition to reducing dependence and consumption of those substances, is to prevent recidivism into drug-related criminal activities.

Country of application
  • United States
Evidence

A systematic review with a meta-analysis indicates a reduction in the use of Class A drugs as a result of redirection to community institutions, as well as a reduction in the use of other drugs. Also, evidence was found that users of Class A drugs were less likely to complete treatment than users of other drugs [1].
At the moment, there is no conclusive evidence of an impact on recidivism reduction. Although some individual studies reveal a modest effect of remission on delinquency, the lack of comparability of outcome measures, heterogeneity, low methodological quality, and paucity of data limit the available evidence, so that the evidence for this outcome variable is uncertain.
