Criminal justice client rehabs can be considered as a significantly better option than time in jail or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for dui of drugs or alcohol may be eligible to get rehabilitation services because of their problem instead of serving time in prison. The judge might order the individual receive rehab, either alone or along with other sentencing. First-time offenders in particular will often be given the opportunity pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they reap the benefits of it if it is an option. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who take part in treatment have a better probability of remaining out of the system after treatment.
