Criminal justice client rehabs are available being a far better option than time in jail or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify for rehabilitation services for his or her problem rather than serving time in jail. The judge might even order the individual receive treatment, either alone or in addition to other consequences. New offenders in particular will often be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is a possibility. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who do take part in rehab have a much better possibility of remaining out of the system after rehabilitation.
