Criminal justice client rehabs can be considered like a considerably better option than incarceration or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. For example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible for rehabilitation services for his or her problem as opposed to serving time in prison. The judge might order the individual receive rehab, either alone or in addition to other consequences. First time offenders specifically are often given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it if it is an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who do experience rehabilitation have a better potential for remaining out of the system following rehab.
