Criminal justice client rehabs can be considered like a far better option than time in jail or heavy fines for those who have been convicted of any type of alcohol or drug related crime. For example, anyone who has been in prison for dui of drugs or alcohol may qualify to receive rehab services for their problem rather than serving time in prison. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. Very first time offenders specifically are often given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it when it is an option. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do experience treatment have a much better potential for remaining out of the system after rehab.
