Criminal justice client rehabs are available as a far better option than time in jail or heavy fines for many who have been convicted of any kind of drug or alcohol related crime. For example, a person who has been found guilty of driving while impaired of drugs or alcohol may be eligible for rehabilitation services for their problem as an alternative to serving time in prison. The judge might order the individual receive treatment, either alone or along with other sentencing. New offenders in particular in many cases are given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it when it is a possibility. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that do experience treatment have a much better possibility of remaining out of the judicial system after rehabilitation.
