Criminal justice client rehabs are available as a considerably better option than time in jail or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for dui of drugs or alcohol may qualify to receive treatment services for his or her problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other consequences. Very first time offenders in particular will often be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it if it is an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehab than punishment. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do experience rehab have a better probability of remaining out of the system after treatment.
