Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services for problem as an alternative to serving time in prison. The judge may even order the individual receive rehab, either alone or along with other consequences. Very first time offenders in particular in many cases are given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it is a choice. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that experience treatment have a much better potential for remaining out of the judicial system following treatment.
