Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, somebody who has been in prison for dui of alcohol or drugs may be eligible for rehab services because of their problem instead of serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other sentencing. First-time offenders specifically will often be given the opportunity select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is an alternative. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehab have a much better chance of remaining out of the system following treatment.
