Criminal justice client rehabs can be considered as being a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For example, anyone who has been in prison for dui of alcohol or drugs may be eligible to receive rehabilitation services because of their problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or as well as other sentencing. First-time offenders specifically in many cases are 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 if it is an alternative. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do take part in rehab have better chance of remaining out of the system after treatment.
