Criminal justice client rehabs are available as being a significantly better option than jail time or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. By way of example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify to obtain treatment services because of their problem instead of serving time in prison. The judge could even order the individual receive rehab, either alone or together with other consequences. First time offenders in particular in many cases are given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into treatment than punishment. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a much better chance of remaining out of the judicial system following rehabilitation.
