Criminal justice client rehabs are available being a considerably better option than prison time or significant fines for individuals who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been found guilty of dui of alcohol or drugs may qualify to obtain rehabilitation services for problem rather than serving time in jail. The judge may even order that the individual receive treatment, either alone or together with other sentencing. First-time offenders specifically tend to be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it when it is a possibility. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done 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 rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do experience rehabilitation have better potential for remaining out of the system following rehab.
