Criminal justice client rehabs can be considered like a far better option than time in jail or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, someone who has been in prison for dui of alcohol or drugs may qualify to obtain treatment services because of their problem as opposed to serving time in jail. The judge might order that the individual receive rehab, either alone or along with other sentencing. First time offenders specifically in many cases are given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it if it is a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been completed to observe how effective this process 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 who do take part in rehab have a much better potential for remaining out of the system after treatment.
