Criminal justice client rehabs are available 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. For instance, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain treatment services for his or her problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders specifically will often be given the opportunity to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it if it's a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do experience rehabilitation have a better possibility of remaining out of the judicial system following treatment.
