Criminal justice client rehabs can be considered being a far better option than prison time or significant fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehab services because of their problem instead of serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular will often be given the ability to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it if it is an option. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been done to discover 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 appear to be quite positive, and criminal justice clients who do experience treatment have a better probability of remaining out of the judicial system following rehabilitation.
