Criminal justice client rehabs are available being a considerably better option than incarceration or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. For instance, someone who has been in prison for dui of drugs or alcohol may qualify to obtain rehabilitation services for his or her problem as opposed to serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular in many cases are given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this strategy 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 take part in treatment have a much better potential for remaining out of the system after treatment.
