Criminal justice client rehabs can be considered like a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. For example, anyone who has been found guilty of driving under the influence of drugs or alcohol may qualify for rehabilitation services because of their problem as opposed to serving time in jail. The judge might even order that the individual receive treatment, either alone or in addition to other consequences. First time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehab have a better possibility of remaining out of the judicial system after rehabilitation.
