Criminal justice client rehabs can be considered as being a significantly better option than prison time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, anyone who has been found guilty of dui of alcohol or drugs may be eligible to receive rehabilitation services because of their problem rather than serving time in prison. The judge may even order the individual receive rehab, either alone or as well as other consequences. First time offenders specifically will often be given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it if it is a choice. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been done to observe 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 appear to be quite positive, and criminal justice clients who do take part in rehab have a better chance of remaining out of the system following treatment.
