Criminal justice client rehabs can be considered as a considerably better option than jail time or significant fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, a person who has been in prison for driving drunk of drugs or alcohol may qualify for rehab services for their problem rather than serving time in jail. The judge could even order that the individual receive rehab, either alone or along with other sentencing. New offenders specifically will often be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehabilitation than punishment. Much research has been completed to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that experience rehabilitation have a much better possibility of remaining out of the system following rehab.
