Criminal justice client rehabs are available like a considerably better option than jail time or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. As an example, somebody who has been in prison for dui of drugs or alcohol may be eligible to obtain rehabilitation services for his or her problem instead of serving time in jail. The judge might even order that the individual receive rehab, either alone or along with other sentencing. Very first time offenders in particular tend to be given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is an alternative. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehab have a much better potential for remaining out of the judicial system following treatment.
