Criminal justice client rehabs are available being a considerably better option than incarceration or significant fines for individuals who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving while impaired of drugs or alcohol may qualify to obtain rehabilitation services for his or her problem as opposed to serving time in prison. The judge could even order the individual receive rehab, either alone or together with other sentencing. First time offenders in particular are often given the chance to select a criminal justice client rehab instead of other sentencing, and it is highly recommended they make the most of it if it's a choice. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into rehab than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that do experience rehab have a better possibility of remaining out of the system following treatment.
