Criminal justice client rehabs can be considered as being a significantly better option than jail time or significant fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, a person who has been in prison for dui of drugs or alcohol may qualify for rehabilitation services for his or her problem as opposed to serving time in prison. The judge could even order the individual receive rehabilitation, either alone or together with other consequences. First-time offenders in particular tend to be given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it if it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab 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 treatment. All indicators seem to be quite positive, and criminal justice clients that experience treatment have better probability of remaining out of the system following treatment.
