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 kind 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 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 in addition to other sentencing. New offenders specifically are often given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it is an option. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into treatment than punishment. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who do experience rehab have a better potential for remaining out of the system following treatment.
