Criminal justice client rehabs can be considered being a far better option than jail time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to get rehab services for his or her problem as opposed to serving time in jail. The judge might order the individual receive rehabilitation, either alone or as well as other consequences. New offenders specifically will often be given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into treatment than punishment. Much research has been completed to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who do experience treatment have better chance of remaining out of the system after rehab.
