Criminal justice client rehabs can be considered like a significantly better option than incarceration or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. By way of example, someone who has been in prison for dui of drugs or alcohol may be eligible for rehabilitation services for their problem as an alternative to serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or together with other consequences. New offenders specifically are often given the ability to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they benefit from it if it is a choice. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a much better potential for remaining out of the judicial system after treatment.
