Criminal justice client rehabs are available as being a far better option than jail time or heavy fines for many who have been convicted of any sort of drug or alcohol related crime. For example, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible to obtain rehab services for problem instead of serving time in jail. The judge may even order the individual receive treatment, either alone or together with other consequences. First time offenders in particular in many cases are given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time 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 rehab. All indicators appear to be quite positive, and criminal justice clients that do experience rehab have a better possibility of remaining out of the judicial system following rehabilitation.
