Criminal justice client rehabs are available as a far better option than incarceration or significant fines for those who have already been convicted of any type of drug or alcohol related crime. For example, someone who has been found guilty of driving while impaired of alcohol or drugs may be eligible for rehab services for his or her problem as opposed to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or along with other consequences. Very first time offenders in particular tend to be given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is an option. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into treatment than punishment. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do experience rehabilitation have a much better possibility of remaining out of the judicial system following rehab.
