Criminal justice client rehabs can be considered being a far better option than time in jail or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible for treatment services because of their problem as an alternative to serving time in jail. The judge might order that the individual receive treatment, either alone or together with other consequences. New offenders specifically tend to be given the chance to go with a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the judicial system following treatment.
