Criminal justice client rehabs are available as a far better option than incarceration or significant fines for those who have been convicted of any type of drug or alcohol related crime. For example, someone who has been in prison for dui of alcohol or drugs may qualify to obtain treatment services for their problem as an alternative to serving time in jail. The judge might even order that the individual receive treatment, either alone or in addition to other sentencing. First-time offenders in particular are often given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it if 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 rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that experience rehabilitation have better probability of remaining out of the judicial system following rehabilitation.
