Criminal justice client rehabs are available as a significantly better option than incarceration or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been in prison for driving under the influence of alcohol or drugs may qualify for rehabilitation services because of their problem instead of serving time in jail. The judge may even order the individual receive treatment, either alone or as well as other sentencing. Very first time offenders specifically are often given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it when it is a choice. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than punishment. Much research has been completed to observe how effective this process 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 take part in treatment have a much better probability of remaining out of the system after rehabilitation.
