Criminal justice client rehabs can be considered like a considerably better option than prison time or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. As an example, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services for their problem instead of serving time in jail. The judge might order that the individual receive rehabilitation, either alone or along with other sentencing. Very first time offenders in particular tend to be given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the individual 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 rehab have a much better potential for remaining out of the judicial system after rehab.
