Criminal justice client rehabs can be considered being a significantly better option than time in jail or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For example, someone who has been in prison for dui of drugs or alcohol may qualify for rehabilitation services for their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehab, either alone or along with other consequences. Very first time offenders in particular tend to be given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been done to find out 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 appear to be quite positive, and criminal justice clients that take part in rehab have a better probability of remaining out of the judicial system following treatment.
