Criminal justice client rehabs can be considered as a significantly better option than incarceration or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to get treatment services for his or her problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it if it's a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this method 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 who take part in rehab have better possibility of remaining out of the judicial system after treatment.
