Criminal justice client rehabs can be considered as being a far better option than jail time or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible to obtain rehab services for their problem rather than serving time in prison. The judge might order that the individual receive treatment, either alone or as well as other sentencing. First time offenders specifically are often given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended 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 commitment into rehabilitation than punishment. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who do experience rehabilitation have a much better probability of remaining out of the judicial system following rehab.
