Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to get treatment services for their problem rather than serving time in prison. The judge may even order that the individual receive treatment, either alone or in addition to other consequences. New offenders in particular tend to 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 if it's a possibility. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into treatment than punishment. Much research has been completed to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that do experience treatment have a much better possibility of remaining out of the system after rehabilitation.
