Criminal justice client rehabs are available as a considerably better option than time in jail or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, somebody who has been found guilty of dui of alcohol or drugs may qualify to receive rehabilitation services for their problem as opposed to serving time in prison. The judge may even order the individual receive rehab, either alone or along with other sentencing. First-time offenders in particular tend to be given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they make the most of it when it is a choice. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into treatment 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 rehab. All indicators seem quite positive, and criminal justice clients who do take part in rehabilitation have better chance of remaining out of the judicial system after rehabilitation.
