Criminal justice client rehabs are available as a considerably better option than jail time or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible for treatment services for their problem as opposed to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or as well as other sentencing. New offenders specifically will often be given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it's a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into treatment than punishment. Much research has been carried out to discover 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 seem to be quite positive, and criminal justice clients who experience rehabilitation have a much better potential for remaining out of the judicial system following rehab.
