Criminal justice client rehabs are available like a far better option than time in jail or significant fines for many who have been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to receive rehab services for problem instead of serving time in prison. The judge might order the individual receive rehabilitation, either alone or together with other sentencing. First time offenders in particular are often given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done 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 appear to be quite positive, and criminal justice clients that experience treatment have a much better potential for remaining out of the judicial system following treatment.
