Criminal justice client rehabs are available as being a far better option than jail time or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for dui of drugs or alcohol may be eligible to obtain rehabilitation services for problem as an alternative to serving time in jail. The judge could even order that the individual receive rehab, either alone or in addition to other consequences. First time offenders specifically will often be given the ability to select a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it when it is an alternative. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to discover 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 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.
