Criminal justice client rehabs are available as a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to get rehab services because of their problem rather than serving time in jail. The judge could even order the individual receive rehab, either alone or along with other consequences. Very first time offenders in particular tend to be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been completed to find out how effective this process 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 that take part in rehabilitation have a much better possibility of remaining out of the judicial system after rehab.
