Criminal justice client rehabs can be considered being a significantly better option than incarceration or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, anyone who has been in prison for driving drunk of drugs or alcohol may qualify to obtain treatment services for his or her problem instead of serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders in particular will often be given the opportunity go with a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it if it is an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who take part in rehab have a better probability of remaining out of the system after rehabilitation.
