Criminal justice client rehabs are available being a far better option than jail time or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been in prison for dui of drugs or alcohol may qualify to get treatment services for problem rather than serving time in prison. The judge may even order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically will often be given the opportunity choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out to see 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 quite positive, and criminal justice clients who take part in treatment have a better possibility of remaining out of the judicial system after treatment.
