Criminal justice client rehabs can be considered being a significantly better option than jail time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible to get rehabilitation services because of their problem as an alternative to serving time in prison. The judge might order that the individual receive treatment, either alone or together with other sentencing. New offenders specifically are often given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to discover 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 do take part in treatment have better chance of remaining out of the system following treatment.
