Criminal justice client rehabs can be considered as being a significantly better option than jail time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible for rehabilitation services because of their problem rather than serving time in jail. The judge could even order the individual receive treatment, either alone or together with other consequences. New offenders specifically in many cases are given the opportunity pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into treatment than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who do experience treatment have a better possibility of remaining out of the system following rehab.
