Criminal justice client rehabs can be considered like a far better option than incarceration or heavy fines for those who have been convicted of any type of alcohol or drug related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive treatment services for their problem as an alternative to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders specifically are often given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they reap the benefits of it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done to discover 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 seem quite positive, and criminal justice clients who do take part in treatment have a better possibility of remaining out of the judicial system after rehabilitation.
