Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, a person who has been in prison for dui of drugs or alcohol may qualify to get rehabilitation services for their problem rather than serving time in prison. The judge may even order the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders in particular tend to be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it when it is a choice. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that take part in rehab have better potential for remaining out of the system after treatment.
