Criminal justice client rehabs can be considered as being a far better option than prison time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving under the influence of alcohol or drugs may qualify to get rehabilitation services because of their problem as opposed to serving time in jail. The judge might even order the individual receive treatment, either alone or as well as other consequences. New offenders specifically will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it if it is an option. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that take part in treatment have a better potential for remaining out of the system following rehabilitation.
