Criminal justice client rehabs are available like a significantly better option than incarceration or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for dui of alcohol or drugs may qualify to obtain rehabilitation services for problem rather than serving time in jail. The judge might even order that the individual receive treatment, either alone or as well as other sentencing. First-time offenders in particular will often be given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it if it's a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out 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 who experience rehabilitation have a much better chance of remaining out of the system after treatment.
