Criminal justice clients are a significant portion of clientele who take part in alcohol and drug rehabilitation programs in Irvington and in the USA. Judges in the U.S. often find it more effective to treat individuals who have ended up in the court system for drug related crimes, rather than penalizing them to no avail with jail time and other such rulings. It has proven more effective to deal with the issue of drug addiction more straightforwardly, rather than invoke these sorts of penalties. Most who do not end up in drug and alcohol rehab will frequently turn right back up in the criminal justice system, whilst criminal justice clients in alcohol and drug rehabilitation generally don't fall back into drug use and have a better chance at remaining abstinent and away from the court system for good.
