Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain rehabilitation services for his or her problem as opposed to serving time in prison. The judge may even order that the individual receive treatment, either alone or along with other sentencing. Very first time offenders in particular will often be given the opportunity select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it when it is a choice. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who do experience rehab have better potential for remaining out of the system following rehab.
