Criminal justice client rehabs can be considered as a significantly better option than time in jail or significant fines for those who have been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for driving while impaired of drugs or alcohol may qualify to obtain rehab services for problem rather than serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders specifically are often given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehab than punishment. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do experience treatment have better chance of remaining out of the judicial system following rehab.
