Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for dui of alcohol or drugs may qualify for rehab services for their problem rather than serving time in prison. The judge may even order the individual receive rehabilitation, either alone or as well as other consequences. New offenders in particular are often given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been carried out to find out 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 appear to be quite positive, and criminal justice clients that take part in treatment have better chance of remaining out of the system following treatment.
