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. By way of example, somebody who has been in prison for dui of drugs or alcohol may be eligible to obtain rehabilitation services for his or her problem rather than serving time in prison. The judge might even order the individual receive treatment, either alone or as well as other sentencing. First time offenders specifically in many cases are given the ability to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it when it is a possibility. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been completed to see how effective this strategy 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 take part in rehab have a better possibility of remaining out of the judicial system after rehab.
