Criminal justice client rehabs can be considered as a far better option than prison time or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For example, somebody who has been found guilty of driving under the influence of alcohol or drugs may qualify for treatment services because of their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders specifically are often given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehabilitation have better chance of remaining out of the judicial system following treatment.
