Criminal justice client rehabs can be considered being a significantly better option than prison time or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For example, somebody who has been in prison for driving while impaired of drugs or alcohol may qualify to receive rehab services for problem as an alternative to serving time in prison. The judge might even order the individual receive rehab, either alone or along with other consequences. New offenders specifically will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it if it is a choice. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. 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 rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better potential for remaining out of the system following rehab.
