Criminal justice client rehabs can be considered like a considerably better option than time in jail or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible for treatment services for their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders specifically tend to be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it when it is a choice. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehab have a much better potential for remaining out of the judicial system after rehab.
