Criminal justice client rehabs can be considered as being a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible to obtain rehab services because of their problem as an alternative to serving time in jail. The judge might even order the individual receive rehab, either alone or as well as other consequences. First-time offenders specifically are often given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this strategy 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 after rehabilitation.
