Criminal justice client rehabs are available as being a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been found guilty of driving drunk of drugs or alcohol may qualify for treatment services for their problem as an alternative to serving time in jail. The judge might order the individual receive treatment, either alone or along with other sentencing. First time offenders specifically tend to be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it is an alternative. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehab have better possibility of remaining out of the judicial system following treatment.
