Criminal justice client rehabs can be considered like a considerably better option than incarceration or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to get rehab services for his or her problem as opposed to serving time in prison. The judge might even order the individual receive treatment, either alone or together with other sentencing. First time offenders specifically are often given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they reap the benefits of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better potential for remaining out of the system after rehabilitation.
