Criminal justice client rehabs can be considered being a significantly better option than incarceration or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For example, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to receive treatment services for his or her problem as opposed to serving time in prison. The judge might order that the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically tend to be given the ability to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it if it is an alternative. The concept 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 done to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that take part in treatment have better possibility of remaining out of the system following rehabilitation.
