Criminal justice client rehabs are available as a considerably better option than time in jail or heavy fines for many who have been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to receive treatment services for his or her problem as an alternative to serving time in prison. The judge might order that the individual receive treatment, either alone or as well as other sentencing. Very first time offenders specifically tend to be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it if it is an option. The idea behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehab than punishment. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do take part in treatment have a much better potential for remaining out of the system after rehab.
