Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for many who have been convicted of any kind of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify for rehabilitation services for his or her problem instead of serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders specifically tend to be given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it if it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who do take part in treatment have a better potential for remaining out of the system after rehab.
