Criminal justice client rehabs can be considered as being a considerably better option than prison time or heavy fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been in prison for dui of drugs or alcohol may qualify to obtain rehabilitation services for his or her problem instead of serving time in jail. The judge might even order the individual receive rehabilitation, either alone or together with other consequences. First-time offenders in particular in many cases are given the ability to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is an option. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that experience rehab have a better possibility of remaining out of the judicial system after rehabilitation.
