Criminal justice client rehabs can be considered like a significantly better option than incarceration or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. By way of example, a person who has been in prison for driving drunk of drugs or alcohol may be eligible to receive treatment services for their problem as opposed to serving time in prison. The judge could even order that the individual receive rehab, either alone or in addition to other sentencing. First time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do take part in rehab have a much better possibility of remaining out of the system following treatment.
