Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible for rehab services for his or her problem rather than serving time in prison. The judge might order that the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders specifically are often given the opportunity select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it when it is an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest commitment into rehab than punishment. Much research has been completed to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do experience treatment have a better possibility of remaining out of the judicial system following treatment.
