Criminal justice client rehabs are available as a significantly better option than prison time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, someone who has been found guilty of driving while impaired of drugs or alcohol may qualify to get rehab services for problem instead of serving time in jail. The judge may even order that the individual receive rehab, either alone or in addition to other sentencing. New offenders in particular tend to be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they reap the benefits of it when it is a possibility. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been completed to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehab have better potential for remaining out of the system following rehabilitation.
