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 kind of drug or alcohol related crime. For example, anyone who has been found guilty of dui of drugs or alcohol may qualify to receive rehab services because of their problem rather than serving time in prison. The judge could even order the individual receive rehab, either alone or together with other sentencing. Very first time offenders specifically are often given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they benefit from it if it is an alternative. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that experience rehab have a better probability of remaining out of the system after treatment.
