Criminal justice client rehabs are available like a considerably better option than jail time or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. For example, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible for treatment services because of their problem instead of serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders specifically will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that experience treatment have a better chance of remaining out of the judicial system after treatment.
