Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. By way of example, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehab services for his or her problem instead of serving time in prison. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. Very first time offenders specifically are often given the chance to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it if it is an alternative. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort 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 individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who do take part in treatment have a better chance of remaining out of the judicial system after treatment.
