Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been found guilty of driving drunk of drugs or alcohol may qualify to receive rehabilitation services for their problem rather than serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or in addition to other consequences. New offenders in particular in many cases are given the chance to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it if it is an option. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a better probability of remaining out of the judicial system following treatment.
