Criminal justice client rehabs are available like a far better option than prison time or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For example, a person who has been in prison for dui of alcohol or drugs may qualify for treatment services for problem as opposed to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders in particular tend to be given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehab have a much better chance of remaining out of the system after rehabilitation.
