Criminal justice client rehabs are available as being a significantly better option than jail time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For instance, anyone who has been found guilty of driving while impaired of alcohol or drugs may qualify to receive rehab services for problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is an option. The idea behind criminal justice client rehabs is it is far more effective and efficient 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 criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do experience treatment have better chance of remaining out of the judicial system after treatment.
