Criminal justice client rehabs can be considered being a considerably better option than time in jail or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, someone who has been found guilty of driving while impaired of alcohol or drugs may qualify to receive rehabilitation services for problem instead of serving time in prison. The judge may even order that the individual receive treatment, either alone or in addition to other sentencing. New offenders specifically in many cases are given the opportunity choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into treatment than punishment. Much research has been carried out 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 that do take part in rehab have better chance of remaining out of the system after rehab.
