Criminal justice client rehabs are available as a far better option than prison time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain rehabilitation services for problem as an alternative to serving time in prison. The judge might even order the individual receive treatment, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it when it is an option. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who do experience rehabilitation have better possibility of remaining out of the judicial system after treatment.
