Criminal justice client rehabs are available as a significantly better option than jail time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of alcohol or drugs may be eligible to get rehabilitation services for their problem as opposed to serving time in jail. The judge might even order the individual receive treatment, either alone or in addition to other consequences. New offenders specifically tend to be given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehab have better possibility of remaining out of the system following treatment.
