Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for driving while impaired of alcohol or drugs may qualify for rehabilitation services for problem as opposed to serving time in prison. The judge might order that the individual receive rehab, either alone or in addition to other consequences. First-time offenders specifically will often be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have a much better probability of remaining out of the judicial system following rehab.
