Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. For example, anyone who has been in prison for dui of drugs or alcohol may qualify to obtain rehabilitation services because of their problem instead of serving time in prison. The judge might order the individual receive rehab, either alone or along with other sentencing. Very first time offenders in particular are often given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it is an option. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab 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 criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better potential for remaining out of the system after rehab.
