Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, somebody who has been found guilty of driving drunk of alcohol or drugs may qualify to receive treatment services for his or her problem as an alternative to serving time in prison. The judge might even order that the individual receive treatment, either alone or in addition to other consequences. Very first time offenders specifically tend to be given the opportunity select a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done 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. The signs and indicators seem quite positive, and criminal justice clients who do take part in rehab have better chance of remaining out of the system after treatment.
