Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been in prison for driving drunk of drugs or alcohol may be eligible for treatment services for problem rather than serving time in jail. The judge might order that the individual receive rehab, either alone or in addition to other sentencing. Very first time offenders specifically are often given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it if it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better potential for remaining out of the judicial system following rehab.
