Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for many who have been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify to get rehab services for his or her problem as an alternative to serving time in jail. The judge might even order that the individual receive rehab, either alone or in addition to other consequences. First-time offenders specifically in many cases are given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits of it when it is an alternative. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have better chance of remaining out of the judicial system following rehabilitation.
