Criminal justice client rehabs can be considered like a significantly better option than time in jail or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible for rehabilitation services because of their problem as an alternative to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or together with other consequences. New offenders specifically in many cases are given the opportunity select a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it if it's a possibility. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehab than punishment. Much research has been carried out to observe 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 appear to be quite positive, and criminal justice clients who take part in rehab have better potential for remaining out of the judicial system after rehab.
