Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been in prison for driving drunk of drugs or alcohol may qualify to get rehab services for problem as an alternative to serving time in jail. The judge could even order that the individual receive rehab, either alone or together with other sentencing. First-time offenders in particular tend to be given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is 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 discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do experience rehab have a much better possibility of remaining out of the system following rehabilitation.
