Criminal justice client rehabs are available as a significantly better option than incarceration or significant fines for many who have been convicted of any kind of drug or alcohol related crime. For example, anyone who has been found guilty of driving while impaired 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 might order that the individual receive treatment, either alone or along with other consequences. Very first time offenders in particular are often given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it if it is a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do experience treatment have better chance of remaining out of the system after rehab.
