Criminal justice client rehabs can be considered as a far better option than time in jail or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been found guilty of driving drunk of alcohol or drugs may be eligible to get rehab services because of their problem as an alternative to serving time in prison. The judge may even order that the individual receive treatment, either alone or together with other sentencing. New offenders in particular will often be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better potential for remaining out of the system following rehab.
