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 alcohol or drug related crime. As an example, someone who has been in prison for driving drunk of drugs or alcohol may qualify to receive treatment services for his or her problem rather than serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other consequences. New offenders specifically will often be given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is a choice. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that experience rehabilitation have better possibility of remaining out of the judicial system following treatment.
