Criminal justice client rehabs are available being a considerably better option than prison time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. By way of example, anyone who has been found guilty of driving under the influence of alcohol or drugs may qualify to get rehab services for his or her problem rather than serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or together with other consequences. New offenders in particular in many cases are given the ability to go with a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into treatment than punishment. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the individual 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 possibility of remaining out of the judicial system following rehab.
