Criminal justice client rehabs are available as being a significantly better option than jail time or significant fines for many who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for dui of drugs or alcohol may be eligible to receive treatment services for his or her problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or in addition to other sentencing. First-time offenders specifically in many cases are given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients who do take part in rehab have a better probability of remaining out of the system after rehabilitation.
