Criminal justice client rehabs are available being a far better option than time in jail or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. As an example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular are often given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it if it's an alternative. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do experience rehab have better probability of remaining out of the system following rehabilitation.
