Criminal justice client rehabs are available as a significantly better option than incarceration or heavy fines for those who have been convicted of any type of drug or alcohol related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to receive treatment services because of their problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders in particular will often be given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it when it is a choice. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into treatment than punishment. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have better potential for remaining out of the system following rehab.
