Criminal justice client rehabs are available as a far better option than time in jail or significant fines for those who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been found guilty of dui of drugs or alcohol may be eligible to obtain treatment services because of their problem as an alternative to serving time in jail. The judge could even order that the individual receive rehab, either alone or in addition to other sentencing. New offenders in particular are often given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it when it is an alternative. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into treatment than punishment. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have a much better probability of remaining out of the system following rehab.
