Criminal justice client rehabs can be considered as a far better option than time in jail or significant fines for those who have been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for dui of drugs or alcohol may be eligible for rehabilitation services for his or her problem as opposed to serving time in jail. The judge might even order that the individual receive treatment, either alone or as well as other sentencing. Very 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 they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this process is on recidivism rates, i.e. if the individual 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 better potential for remaining out of the system after rehabilitation.
