Criminal justice client rehabs are available as being a considerably better option than jail time or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. By way of example, a person who has been found guilty of driving under the influence of alcohol or drugs may qualify to get rehabilitation services because of their problem rather than serving time in prison. The judge might even order the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders in particular in many cases are given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done 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 treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have better chance of remaining out of the judicial system following treatment.
