Criminal justice client rehabs are available as a far better option than prison time or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. For instance, somebody who has been found guilty of driving under the influence of drugs or alcohol may qualify for rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order that the individual receive rehab, either alone or together with other sentencing. New offenders in particular will often be given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been done 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 rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in treatment have better chance of remaining out of the judicial system following rehabilitation.
