Criminal justice client rehabs can be considered like a far better option than incarceration or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For example, someone who has been in prison for dui of alcohol or drugs may qualify to receive rehabilitation services for his or her problem instead of serving time in prison. The judge could even order that the individual receive rehab, either alone or in addition to other consequences. First time offenders specifically tend to be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it when it is an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who experience treatment have a much better possibility of remaining out of the judicial system after rehabilitation.
