Criminal justice client rehabs are available as a significantly better option than prison time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible to receive treatment services for his or her problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or together with other consequences. First-time offenders in particular in many cases are given the ability to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it if it's an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into treatment than punishment. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that take part in treatment have better possibility of remaining out of the judicial system after rehabilitation.
