Criminal justice client rehabs can be considered like a significantly better option than time in jail or significant fines for those who have been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving under the influence of alcohol or drugs may qualify to receive rehab services for their problem as an alternative to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or together with other sentencing. New offenders in particular in many cases are given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have a much better potential for remaining out of the judicial system after rehab.
