Criminal justice client rehabs can be considered as a considerably better option than incarceration or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for dui of drugs or alcohol may be eligible to receive rehab services for their problem rather than serving time in prison. The judge may even order the individual receive rehabilitation, either alone or as well as other consequences. First time offenders specifically will often be given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it when it is a possibility. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to see how effective this method 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 who do take part in rehab have better possibility of remaining out of the system after rehab.
