Criminal justice client rehabs can be considered as a significantly better option than jail time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may qualify to get rehabilitation services for their problem rather than serving time in prison. The judge may even order the individual receive rehab, either alone or together with other consequences. New offenders in particular will often be given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it's an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into treatment than enforcement of other consequences. Much research has been done to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do take part in rehabilitation have a much better potential for remaining out of the system after treatment.
