Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for driving drunk of drugs or alcohol may be eligible for rehabilitation services for his or her problem as an alternative to serving time in jail. The judge could even order the individual receive treatment, either alone or in addition to other sentencing. New offenders specifically in many cases are given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been completed 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 who do experience treatment have better probability of remaining out of the system after rehab.
