Criminal justice client rehabs can be considered like a considerably better option than prison time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services for their problem as an alternative to serving time in prison. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. New offenders specifically are often given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehab have a much better possibility of remaining out of the system following rehab.
