Criminal justice client rehabs are available as a considerably better option than incarceration or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. By way of example, somebody who has been found guilty of driving under the influence of drugs or alcohol may be eligible to obtain rehab services for their problem as opposed to serving time in jail. The judge might order that the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders in particular are often given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it when it is an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do take part in treatment have a better chance of remaining out of the system after rehab.
