Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for many who have been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been found guilty of driving under the influence of drugs or alcohol may be eligible to receive treatment services for their problem instead of serving time in prison. The judge could even order the individual receive rehab, either alone or along with other consequences. Very first time offenders in particular will often be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into rehabilitation than punishment. 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 rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehab have better chance of remaining out of the system after rehabilitation.
