Criminal justice client rehabs can be considered like a significantly better option than prison time or significant fines for individuals who have already been convicted of any kind 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 for rehab services for their problem rather than serving time in prison. The judge may even order the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders specifically are often given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehab than punishment. Much research has been completed to see how effective this process is on recidivism rates, i.e. if the individual 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 rehabilitation have a better chance of remaining out of the judicial system after rehab.
