Criminal justice client rehabs are available being a far better option than incarceration or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been in prison for dui of alcohol or drugs may be eligible to obtain rehab services for his or her problem as an alternative to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or along with other sentencing. New offenders in particular will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it when it is an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to see 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 who do experience rehabilitation have a better possibility of remaining out of the judicial system after treatment.
