Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been in prison for driving under the influence of alcohol or drugs may qualify for rehabilitation services for his or her problem instead of serving time in prison. The judge could even order that the individual receive rehab, either alone or together with other sentencing. First time offenders specifically in many cases are given the chance to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it if it's a choice. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than punishment. Much research has been completed to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that experience rehabilitation have better chance of remaining out of the system following treatment.
