Criminal justice client rehabs are available as being a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, somebody who has been found guilty of driving while impaired of alcohol or drugs may be eligible for rehabilitation services for his or her problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or together with other sentencing. First time offenders specifically will often be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it is an option. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been done 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 treatment. All indicators seem quite positive, and criminal justice clients who do take part in rehabilitation have a better chance of remaining out of the system following rehabilitation.
