Criminal justice client rehabs are available being a significantly better option than incarceration or heavy fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, anyone who has been found guilty of driving while impaired of drugs or alcohol may be eligible for rehab services because of their problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other sentencing. Very first time offenders in particular are often given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual 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 a much better possibility of remaining out of the judicial system after treatment.
