Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been found guilty of driving drunk of alcohol or drugs may qualify to get rehabilitation services because of their problem as an alternative to serving time in jail. The judge may even order that the individual receive treatment, either alone or as well as other sentencing. First-time offenders specifically will often be given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they reap the benefits of it if it is a possibility. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been carried out 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 rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehab have a better possibility of remaining out of the judicial system after rehab.
