Criminal justice client rehabs can be considered as a far better option than prison time or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehab services for their problem as an alternative to serving time in jail. The judge may even order that the individual receive rehab, either alone or as well as other consequences. First time offenders specifically in many cases are given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this method 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 experience rehab have better chance of remaining out of the judicial system after treatment.
