Criminal justice client rehabs can be considered as being a significantly better option than jail time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. For instance, someone who has been in prison for dui of drugs or alcohol may qualify to get rehab services for problem as opposed to serving time in prison. The judge might even order that the individual receive rehab, either alone or in addition to other sentencing. First-time offenders specifically are often given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it when it is a possibility. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a better potential for remaining out of the judicial system following rehab.
