Criminal justice client rehabs can be considered being a far better option than incarceration or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For instance, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible for rehabilitation services because of their problem instead of serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other consequences. First-time offenders in particular tend to be given the opportunity pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort 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 appear to be quite positive, and criminal justice clients that do experience rehabilitation have a much better possibility of remaining out of the judicial system following treatment.
