Criminal justice client rehabs are available as a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, anyone who has been found guilty of dui of drugs or alcohol may qualify to receive treatment services for his or her problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically will often be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it when it is an option. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to find out how effective this approach 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 experience treatment have better possibility of remaining out of the system after treatment.
