Criminal justice client rehabs can be considered as a far better option than incarceration or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been in prison for driving drunk of alcohol or drugs may qualify to receive rehabilitation services for problem rather than serving time in prison. The judge may even order that the individual receive treatment, either alone or together with other sentencing. New offenders in particular tend to be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it if it is a possibility. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been completed to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that do experience treatment have a much better probability of remaining out of the system after treatment.
