Criminal justice client rehabs are available as being a significantly better option than prison time or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. For example, a person who has been found guilty of driving drunk of drugs or alcohol may qualify to receive treatment services because of their problem as an alternative to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or as well as other sentencing. Very first time offenders in particular tend to be given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it if it is an alternative. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been done to see how effective this method is on recidivism rates, i.e. if the individual 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 treatment have a better potential for remaining out of the system following rehab.
