Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. By way of example, someone who has been in prison for driving under the influence of alcohol or drugs may qualify for rehabilitation services for his or her problem instead of serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or along with other consequences. New offenders specifically in many cases are given the ability to select a criminal justice client rehab instead of 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 way more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do experience rehabilitation have a much better probability of remaining out of the system after rehabilitation.
