Criminal justice client rehabs are available like a far better option than prison time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible to obtain treatment services for their problem as an alternative to serving time in prison. The judge could even order that the individual receive treatment, either alone or together with other consequences. New offenders specifically will often be given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it if it's a choice. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to observe 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 do experience rehabilitation have a better chance of remaining out of the system following rehabilitation.
