Criminal justice client rehabs are available being a considerably better option than prison time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible to receive treatment services because of their problem rather than serving time in jail. The judge might order that the individual receive rehab, either alone or along with other sentencing. New offenders in particular in many cases are given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised they reap the benefits of it when it is a choice. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do take part in rehab have better probability of remaining out of the system following rehab.
