Criminal justice client rehabs can be considered as a significantly better option than time in jail or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehab services for their problem instead of serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders specifically are often given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been completed to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who do take part in treatment have a better potential for remaining out of the judicial system after treatment.
