Criminal justice client rehabs can be considered as a far better option than prison time or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehab services for problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically will often be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it when it is a possibility. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been completed to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better chance of remaining out of the system after treatment.
