Criminal justice client rehabs are available as a significantly better option than jail time or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been in prison for dui of drugs or alcohol may qualify to get treatment services because of their problem rather than serving time in jail. The judge may even order the individual receive treatment, either alone or in addition to other consequences. First-time offenders in particular will often be given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is an option. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been done 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. All indicators seem quite positive, and criminal justice clients who do take part in treatment have better chance of remaining out of the system after treatment.
