Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For example, a person who has been found guilty of driving drunk of drugs or alcohol may be eligible to get rehab services for his or her problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders specifically will often be given the chance to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do experience treatment have better probability of remaining out of the system following rehab.
