Criminal justice client rehabs can be considered as a considerably better option than incarceration or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been in prison for driving drunk of alcohol or drugs may qualify to obtain treatment services for his or her problem as opposed to serving time in jail. The judge may even order that the individual receive treatment, either alone or together with other consequences. First-time offenders in particular will often be given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it when it is a possibility. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been completed to find out how effective this process 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 to be quite positive, and criminal justice clients that do take part in rehab have a much better chance of remaining out of the judicial system following treatment.
