For instance, anyone who has been found guilty of dui of drugs or alcohol may be eligible for rehab services for problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or as well as other consequences. First time offenders in particular are often given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it when it is a possibility.

Much research has been done to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do take part in rehab have a better chance of remaining out of the system after treatment.
