Criminal justice client rehabs can be considered as a significantly better option than time in jail or significant fines for many who have already been convicted of any sort of alcohol or drug related crime. For example, a person who has been in prison for driving drunk of drugs or alcohol may be eligible for treatment services for their problem instead of serving time in prison. The judge might order that the individual receive treatment, either alone or in addition to other consequences. First time offenders in particular in many cases are given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they reap the benefits of it if it is an alternative. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into rehab than punishment. Much research has been completed to find out 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 seem to be quite positive, and criminal justice clients that do experience treatment have a much better potential for remaining out of the system after treatment.
