Criminal justice client rehabs can be considered as a significantly better option than prison time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been found guilty of driving under the influence of drugs or alcohol may be eligible to get rehab services for his or her problem instead of serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders specifically are often given the ability to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an option. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been completed to observe 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 who do experience rehab have better possibility of remaining out of the system after treatment.
