Criminal justice client rehabs can be considered as being a significantly better option than time in jail or significant fines for many who have already been convicted of any type of drug or alcohol related crime. For instance, someone who has been in prison for dui of alcohol or drugs may be eligible to receive treatment services for his or her problem instead of serving time in prison. The judge may even order the individual receive treatment, either alone or in addition to other consequences. New offenders in particular will often be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been done to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a better potential for remaining out of the judicial system after treatment.
