Criminal justice client rehabs are available being a considerably better option than jail time or significant fines for those who have been convicted of any kind of drug or alcohol related crime. As an example, a person who has been in prison for driving drunk of drugs or alcohol may qualify to get treatment services because of their problem rather than serving time in jail. The judge could even order the individual receive treatment, either alone or in addition to other consequences. Very first time offenders in particular are often given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort 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 rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have a better potential for remaining out of the judicial system following rehabilitation.
