Criminal justice client rehabs are available as being a far better option than jail time or heavy fines for many who have already been convicted of any kind of drug or alcohol related crime. For example, a person who has been found guilty of dui of drugs or alcohol may be eligible to obtain rehab services for their problem as opposed to serving time in prison. The judge could even order the individual receive treatment, either alone or in addition to other sentencing. First time offenders specifically tend to be given the chance to select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it if it's a possibility. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have a better chance of remaining out of the system following treatment.
