Criminal justice client rehabs are available as a far better option than jail time or significant fines for many who have already been convicted of any type of drug or alcohol related crime. For example, anyone who has been found guilty of dui of alcohol or drugs may be eligible for treatment services for problem as an alternative to serving time in jail. The judge might order that the individual receive treatment, either alone or in addition to other consequences. First-time offenders specifically in many cases are given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it is a choice. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been completed to observe how effective this process 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 to be quite positive, and criminal justice clients that do take part in rehabilitation have better chance of remaining out of the judicial system following rehabilitation.
