Criminal justice clients are a large percentage of clientele who take part in drug treatment facilities in Roggen and in the USA. Judicial systems in the U.S. often find it more effective to rehab people who have wound up in the criminal justice system for drug related crimes, instead of punishing them in vain with jail time and other such rulings. It has proven more successful to deal with the trouble of drug addiction more straightforwardly, rather than invoke these sorts of penalties. The majority of who do not make their way to drug and alcohol treatment will often turn right back up in the criminal justice hamster wheel, whilst criminal justice clients in drug rehab generally don't fall back into drug use and have a better chance at staying abstinent and out of the court system entirely.
