Criminal justice client rehabs can be considered like a considerably better option than jail time or heavy fines for individuals who have been convicted of any sort of alcohol or drug related crime. For example, a person who has been in prison for dui of drugs or alcohol may qualify for rehab services for their problem rather than serving time in prison. The judge may even order the individual receive treatment, either alone or along with other sentencing. New offenders specifically will often be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who do take part in rehabilitation have a much better chance of remaining out of the system after treatment.
