Criminal justice client rehabs are available like a far better option than jail time or significant fines for those who have been convicted of any sort of alcohol or drug related crime. By way of example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to get rehabilitation services because of their problem as opposed to serving time in prison. The judge may even order the individual receive rehab, either alone or as well as other sentencing. New offenders in particular in many cases are given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that experience rehab have better probability of remaining out of the judicial system following rehab.
