Criminal justice client rehabs are available as a significantly better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. By way of example, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible to obtain rehab services for his or her problem instead of serving time in jail. The judge may even order the individual receive rehab, either alone or as well as other consequences. First time offenders specifically tend to be given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it's an alternative. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who do experience rehab have a much better possibility of remaining out of the judicial system following rehabilitation.
