Criminal justice client rehabs are available like a far better option than incarceration or heavy fines for individuals 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 receive rehabilitation services for his or her problem rather than serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or along with other sentencing. New offenders specifically are often given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it if it is an option. The theory behind criminal justice client rehabs is it is way 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 method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do experience rehab have a better possibility of remaining out of the system following rehab.
