Criminal justice client rehabs can be considered like a considerably better option than prison time or significant fines for individuals who have been convicted of any kind of alcohol or drug related crime. For example, someone who has been in prison for driving drunk of alcohol or drugs may be eligible to receive treatment services for their problem as an alternative to serving time in prison. The judge might order the individual receive treatment, either alone or together with other sentencing. First-time offenders specifically are often given the chance to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of 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 rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that take part in rehabilitation have a much better potential for remaining out of the judicial system after treatment.
