Criminal justice client rehabs are available being a considerably better option than jail time or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify to get treatment services because of their problem rather than serving time in prison. The judge might order that the individual receive rehab, either alone or together with other consequences. First time offenders in particular tend to be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they reap the benefits of it if it is a choice. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into treatment than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All 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.
