Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for many who have been convicted of any sort of alcohol or drug related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to receive rehab services because of their problem as an alternative to serving time in prison. The judge might order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically will often be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they reap the benefits of it if it's a choice. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into treatment than enforcement of other consequences. Much research has been done to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better chance of remaining out of the system following rehabilitation.
