Criminal justice client rehabs are available like a significantly better option than prison time or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify for treatment services for their problem as opposed to serving time in prison. The judge might even order that the individual receive treatment, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it when it is an alternative. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehabilitation have a much better probability of remaining out of the system after rehabilitation.
