Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive treatment services because of their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. New offenders specifically tend to be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it if it's an option. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehab than punishment. Much research has been completed to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehabilitation have a better chance of remaining out of the system following treatment.
