Criminal justice client rehabs are available like a considerably better option than jail time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. As an example, someone who has been in prison for driving under the influence of drugs or alcohol may qualify for rehabilitation services for problem as an alternative to serving time in jail. The judge might even order the individual receive rehabilitation, either alone or together with other consequences. First-time offenders specifically are often given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is an option. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have better probability of remaining out of the judicial system following rehabilitation.
