Criminal justice client rehabs can be considered as a considerably better option than prison time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. By way of example, someone who has been found guilty of dui of drugs or alcohol may qualify to get rehab services for his or her problem rather than serving time in jail. The judge might order the individual receive treatment, either alone or in addition to other sentencing. Very first time offenders in particular in many cases are given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an option. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that do experience rehab have better chance of remaining out of the system after treatment.
