Criminal justice client rehabs are available as a significantly 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 example, someone who has been found guilty of dui of drugs or alcohol may qualify to obtain treatment services for their problem instead of serving time in jail. The judge might even order the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular in many cases are given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into rehab than punishment. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do experience treatment have a much better potential for remaining out of the system after rehab.
