Criminal justice client rehabs are available as a far better option than jail time or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible for rehab services because of their problem as an alternative to serving time in jail. The judge might order that the individual receive rehab, either alone or along with other sentencing. First-time offenders specifically will often be given the chance to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it if it's a choice. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into treatment than enforcement of other consequences. 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 appear to be quite positive, and criminal justice clients who experience rehab have better potential for remaining out of the system after rehabilitation.
