Criminal justice client rehabs can be considered being a far better option than incarceration or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been in prison for driving under the influence of alcohol or drugs may qualify to get rehab services for his or her problem rather than serving time in jail. The judge could even order that the individual receive treatment, either alone or in addition to other consequences. First-time offenders in particular are often given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it if it is a possibility. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who take part in treatment have a better potential for remaining out of the system following rehab.
