Criminal justice client rehabs can be considered as being a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. For instance, someone who has been in prison for dui of drugs or alcohol may qualify for rehabilitation services for his or her problem as an alternative to serving time in prison. The judge could even order the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders specifically in many cases are given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it if it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been completed to find out how effective this strategy 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 experience rehab have a much better probability of remaining out of the system following treatment.
