Criminal justice client rehabs are available as a significantly better option than time in jail or heavy fines for many who have been convicted of any sort of alcohol or drug related crime. As an example, someone who has been in prison for dui of alcohol or drugs may be eligible to obtain rehab services for their problem as an alternative to serving time in jail. The judge may even order the individual receive treatment, either alone or as well as other sentencing. First time offenders in particular will often be given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time 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 criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a much better possibility of remaining out of the system after rehabilitation.
