Criminal justice client rehabs can be considered as a considerably better option than time in jail or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been in prison for driving while impaired of drugs or alcohol may qualify for rehab services for his or her problem as opposed to serving time in jail. The judge might even order the individual receive rehab, either alone or in addition to other consequences. New offenders in particular are often given the opportunity choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it when it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have a much better possibility of remaining out of the judicial system following rehab.
