Criminal justice client rehabs are available as a significantly better option than incarceration or significant fines for many who have already been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain treatment services because of their problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or together with other consequences. First time offenders specifically will often be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into treatment than punishment. Much research has been completed to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who do experience rehabilitation have a better probability of remaining out of the judicial system following treatment.
