Criminal justice client rehabs are available as a considerably better option than jail time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain treatment services because of their problem as opposed to serving time in prison. The judge might order the individual receive rehabilitation, either alone or as well as other sentencing. Very first time offenders in particular in many cases are given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to observe 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 who do experience rehab have a much better probability of remaining out of the judicial system after rehabilitation.
