Criminal justice client rehabs can be considered as being a significantly better option than prison time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible for treatment services for their problem as opposed to serving time in prison. The judge might order that the individual receive treatment, either alone or together with other consequences. First-time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they reap the benefits of it when it is an alternative. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that do experience treatment have a much better probability of remaining out of the system following rehab.
