Criminal justice client rehabs can be considered as being a far better option than jail time or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. As an example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem as an alternative to serving time in jail. The judge might order that the individual receive treatment, either alone or in addition to other sentencing. New offenders in particular will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have better chance of remaining out of the system following treatment.
