Criminal justice client rehabs can be considered as being a significantly better option than prison time or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. As an example, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services because of their problem as an alternative to serving time in prison. The judge might even order that the individual receive rehab, either alone or along with other sentencing. New offenders in particular in many cases are given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it if it's a choice. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do experience treatment have a much better chance of remaining out of the judicial system following rehabilitation.
