Criminal justice client rehabs are available as 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 instance, someone who has been found guilty of driving under the influence of drugs or alcohol may qualify for treatment services for his or her problem instead of serving time in jail. The judge might even order the individual receive treatment, either alone or along with other sentencing. First-time offenders specifically will often be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest commitment into treatment than punishment. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do take part in treatment have a much better probability of remaining out of the system after rehab.
