Criminal justice client rehabs are available like a considerably better option than jail time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehabilitation services for their problem instead of serving time in jail. The judge might order that the individual receive treatment, either alone or in addition to other consequences. First time offenders specifically in many cases are given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that take part in rehabilitation have a much better potential for remaining out of the judicial system after rehab.
