Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. For example, somebody who has been in prison for driving while impaired of drugs or alcohol may qualify for rehab services because of their problem instead of serving time in jail. The judge might even order that the individual receive treatment, either alone or as well as other sentencing. First time offenders in particular are often given the chance to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended 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 done 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 seem to be quite positive, and criminal justice clients who do experience rehabilitation have a better chance of remaining out of the system following rehab.
