Criminal justice client rehabs can be considered being a considerably better option than incarceration or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, someone who has been in prison for driving drunk of alcohol or drugs may be eligible to obtain rehabilitation services for problem instead of serving time in jail. The judge could even order the individual receive rehab, either alone or together with other sentencing. New offenders in particular will often be given the opportunity select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it when it is an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this method 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 to be quite positive, and criminal justice clients who experience rehabilitation have a better chance of remaining out of the judicial system following rehab.
