Criminal justice client rehabs are available like a significantly better option than prison time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain rehabilitation services for their problem rather than serving time in jail. The judge might order that the individual receive rehab, either alone or in addition to other sentencing. First time offenders in particular will often be given the chance to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it if it is a choice. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who do experience rehab have better probability of remaining out of the judicial system following rehab.
