Criminal justice client rehabs can be considered being a significantly better option than jail time or significant fines for those 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 receive rehabilitation services for his or her problem instead of serving time in jail. The judge might order the individual receive treatment, either alone or as well as other consequences. New offenders in particular in many cases are given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is well-advised 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 time and energy into rehab than enforcement of other consequences. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in treatment have a better possibility of remaining out of the judicial system following rehab.
