Criminal justice client rehabs are available being a far better option than incarceration or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been in prison for dui of drugs or alcohol may qualify for rehabilitation services for their problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other sentencing. New offenders specifically are often given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is an option. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been completed 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 rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that take part in treatment have a better potential for remaining out of the judicial system following rehabilitation.
