Criminal justice clients are a significant percentage of clientele who take part in drug rehab facilities in Derry and across the nation. Court systems in the U.S. are finding it more effective to treat individuals who have found their way into the criminal justice system for crimes relating to drugs, rather than penalizing them to no avail with time in jail and other such rulings. It has proven more effective to deal with the issue of addiction more straightforwardly, rather than enforce these sorts of penalties. The majority of individuals who do not make their way to drug rehab will typically turn right back up in the criminal justice hamster wheel, while criminal justice clients in drug and alcohol rehab often don't fall back into drug use and have a better chance at staying sober and out of the court system entirely.
