Criminal justice client rehabs can be considered being a significantly better option than prison time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for driving under the influence of alcohol or drugs may qualify for rehabilitation services for problem instead of serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other consequences. New offenders specifically will often be given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it if it's a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client 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 possibility of remaining out of the system following treatment.
