Criminal justice client rehabs are available being a significantly better option than incarceration or heavy fines for individuals who have been convicted of any kind of drug or alcohol related crime. As an example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible for rehab services for their problem as an alternative to serving time in prison. The judge might order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically are often given the ability to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they reap the benefits of it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have a much better potential for remaining out of the judicial system after rehab.
