Criminal justice client rehabs can be considered like a significantly better option than prison time or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, someone who has been in prison for dui of alcohol or drugs may qualify to receive rehabilitation services because of their problem instead of serving time in prison. The judge might order that the individual receive treatment, either alone or along with other sentencing. Very first time offenders in particular in many cases are given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is a choice. The idea behind criminal justice client rehabs is that it is much more effective and efficient 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. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehab have a better possibility of remaining out of the judicial system after treatment.
