Criminal justice client rehabs are available as a far better option than incarceration or heavy fines for those who have been convicted of any kind of alcohol or drug related crime. For example, anyone who has been found guilty of driving while impaired of drugs or alcohol may qualify to obtain treatment services for problem rather than serving time in jail. The judge might order the individual receive rehabilitation, either alone or as well as other consequences. First time offenders in particular in many cases are given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into rehab than punishment. Much research has been done to discover how effective this approach 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 that do experience treatment have better potential for remaining out of the judicial system following treatment.
