Criminal justice client rehabs are available as a considerably better option than incarceration or significant fines for those who have already been convicted of any type of drug or alcohol related crime. For instance, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehabilitation services for their problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or as well as other consequences. First time offenders in particular are often given the opportunity select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it if it is a possibility. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy 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 individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do take part in rehab have better possibility of remaining out of the system following rehabilitation.
