Criminal justice client rehabs can be considered as being a significantly better option than prison time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been in prison for dui of drugs or alcohol may be eligible to get rehabilitation services for problem as an alternative to serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically in many cases are given the chance to go with a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it if it is a choice. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have a better probability of remaining out of the system following treatment.
