Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. As an example, a person who has been found guilty of dui of drugs or alcohol may be eligible to get rehabilitation services for problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or along with other sentencing. First time offenders in particular tend to be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it when it is a possibility. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into treatment than punishment. Much research has been done to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a better potential for remaining out of the system after treatment.
