Criminal justice client rehabs are available being a significantly better option than prison time or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, someone who has been found guilty of dui of alcohol or drugs may qualify to receive treatment services for their problem rather than serving time in prison. The judge might order that the individual receive treatment, either alone or together with other sentencing. First time offenders in particular tend to be given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it when it is a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out 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 rehab. All indicators seem quite positive, and criminal justice clients who experience rehab have a better chance of remaining out of the system following rehab.
