Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For instance, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehab services because of their problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or along with other sentencing. New offenders specifically will often be given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it if it's a choice. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time 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 chance of remaining out of the judicial system following rehab.
