Criminal justice client rehabs can be considered as being a far better option than prison time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving while impaired of drugs or alcohol may qualify to receive rehabilitation services for his or her problem as an alternative to serving time in prison. The judge may even order the individual receive treatment, either alone or as well as other sentencing. First-time offenders in particular are often given the chance to select 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 a choice. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into treatment than punishment. Much research has been done to discover how effective this process 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 to be quite positive, and criminal justice clients who do experience rehab have a much better probability of remaining out of the judicial system after rehab.
