Criminal justice clients are a considerable percentage of clientele who take part in drug rehab centers in Vienna and in the USA. Court systems in the country often find it more effective to rehab people who have wound up in the court system for drug related crimes, rather than penalizing them to no avail with jail time and other penalties. It is proven to be more helpful to address the problem of drug addiction more straightforwardly, than to enforce these sorts of penalties. Most who do not end up in alcohol and drug rehab will often turn right back up in the criminal justice system, whilst criminal justice clients in drug and alcohol rehabilitation often don't fall back into drug use and have a much better chance at staying abstinent and out of the court system for good.
