Criminal justice client rehabs are available as being a significantly better option than prison time or heavy fines for many who have already been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to get rehabilitation services for problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other sentencing. New offenders in particular will often be given the opportunity select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it's a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehabilitation have better potential for remaining out of the system following rehab.
