Criminal justice client rehabs are available as a significantly better option than incarceration or significant fines for many who have been convicted of any type of drug or alcohol related crime. By way of example, a person who has been found guilty of driving under the influence of alcohol or drugs may qualify for rehab 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 together with other sentencing. First-time offenders specifically in many cases are given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it if it is a choice. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the criminal justice client 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 treatment have better potential for remaining out of the system after rehabilitation.
