Criminal justice client rehabs are available as a considerably better option than jail time or significant fines for individuals who have been convicted of any sort of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services because of their problem as an alternative to serving time in prison. The judge might even order the individual receive rehab, either alone or together with other consequences. New offenders specifically are often given the chance to select 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 an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehab than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who take part in treatment have a better possibility of remaining out of the system following treatment.
