Criminal justice client rehabs can be considered as being a significantly better option than jail time or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to get treatment services for their problem as an alternative to serving time in prison. The judge could 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 pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it if it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a better probability of remaining out of the judicial system after treatment.
