Criminal justice client rehabs are available being a significantly better option than prison time or significant fines for individuals who have been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible for treatment services because of their problem as an alternative to serving time in prison. The judge might even order the individual receive rehab, either alone or together with other consequences. First-time offenders specifically are often given the chance to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehab have a better chance of remaining out of the judicial system following treatment.
