Criminal justice client rehabs are available as being a significantly better option than incarceration or significant fines for many who have been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehab services for their problem rather than serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or along with other consequences. First-time offenders in particular are often given the ability to select a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client 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 rehabilitation have a better possibility of remaining out of the system following treatment.
