Criminal justice client rehabs can be considered as being a far better option than jail time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving under the influence of drugs or alcohol may qualify to receive rehabilitation services for his or her problem rather than serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. Very first time offenders specifically will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehabilitation have a much better chance of remaining out of the judicial system following treatment.
