Criminal justice client rehabs are available as being a considerably better option than prison time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. As an example, a person who has been found guilty of dui of drugs or alcohol may qualify to get rehabilitation services because of their problem as opposed to serving time in prison. The judge might order the individual receive rehab, either alone or together with other sentencing. First time offenders specifically are often given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it when it is a choice. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into treatment than punishment. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that take part in treatment have a much better potential for remaining out of the system after rehabilitation.
