Criminal justice client rehabs can be considered like a considerably better option than time in jail or significant fines for those who have been convicted of any type of alcohol or drug related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem instead of serving time in prison. The judge may even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in treatment have a much better chance of remaining out of the system following treatment.
