Criminal justice client rehabs are available being a far better option than incarceration or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to receive rehab services for his or her problem instead of serving time in prison. The judge might order that the individual receive rehab, either alone or as well as other consequences. First-time offenders in particular will often be given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it if it is a choice. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who do experience rehab have a better potential for remaining out of the judicial system after treatment.
