Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving drunk of drugs or alcohol may be eligible to obtain rehab services for their problem as opposed to serving time in prison. The judge might order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically will often be given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it if it is a possibility. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort 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 criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehabilitation have better probability of remaining out of the judicial system following rehabilitation.
