Criminal justice client rehabs are available as being a significantly better option than incarceration or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. As an example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem instead of serving time in jail. The judge might order that the individual receive treatment, either alone or together with other sentencing. New offenders specifically will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it when it is a choice. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into treatment than punishment. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in treatment have a better potential for remaining out of the judicial system after rehab.
