Criminal justice client rehabs can be considered as a significantly better option than jail time or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. As an example, a person who has been in prison for dui of drugs or alcohol may qualify to get rehabilitation services because of their problem instead of serving time in jail. The judge may even order the individual receive rehabilitation, either alone or along with other sentencing. New offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it if it is a possibility. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehab than punishment. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who take part in rehab have better potential for remaining out of the system following rehabilitation.
