Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. For example, someone who has been found guilty of driving drunk of drugs or alcohol may be eligible to get rehab services because of their problem instead of serving time in prison. The judge may even order the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically tend to be given the opportunity select a criminal justice client rehab instead of other sentencing, and it is highly recommended they benefit from it when it is a choice. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehab than punishment. Much research has been done to observe 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 appear to be quite positive, and criminal justice clients who do take part in treatment have a better possibility of remaining out of the system after rehab.
