Criminal justice client rehabs are available as a far better option than prison time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, someone who has been found guilty of driving under the influence of drugs or alcohol may qualify to get treatment services for their problem as opposed to serving time in jail. The judge might even order the individual receive treatment, either alone or together with other consequences. First time offenders in particular are often given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it if it's a possibility. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who take part in rehab have better possibility of remaining out of the system after rehabilitation.
