Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services because of their problem rather than serving time in jail. The judge may even order that the individual receive rehab, either alone or as well as other sentencing. First time offenders specifically will often be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is a possibility. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to see how effective this process 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 treatment have a much better possibility of remaining out of the judicial system after rehab.
