Criminal justice client rehabs are available like a significantly better option than jail time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, anyone who has been found guilty of driving drunk of alcohol or drugs may qualify to receive treatment services for problem as an alternative to serving time in jail. The judge might order that the individual receive rehab, either alone or together with other consequences. First-time offenders in particular are often given the opportunity choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have better chance of remaining out of the judicial system following treatment.
