Criminal justice client rehabs are available like a considerably better option than jail time or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. As an example, someone who has been in prison for driving under the influence of alcohol or drugs may be eligible to get rehab services for his or her problem instead of serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other consequences. First-time offenders specifically are often given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage 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 rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a much better chance of remaining out of the system following rehab.
