Criminal justice client rehabs can be considered as a considerably better option than time in jail or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving drunk of drugs or alcohol may be eligible to receive treatment services for problem as opposed to serving time in jail. The judge could even order the individual receive rehab, either alone or along with other consequences. First time offenders specifically are often given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehab than punishment. Much research has been done to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have a better possibility of remaining out of the judicial system following treatment.
