Criminal justice client rehabs can be considered as being a significantly better option than jail time or significant fines for those who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been found guilty of dui of drugs or alcohol may be eligible for rehabilitation services for his or her problem as an alternative to serving time in jail. The judge may even order that the individual receive rehab, either alone or in addition to other consequences. First time offenders specifically are often given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it if it is an option. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab than punishment. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a better possibility of remaining out of the judicial system after treatment.
