Criminal justice clients are a large percentage of clients who take part in drug and alcohol rehab centers in Boston, New York and across the nation. Court systems around the country often find it more effective to rehabilitate men and women who have found their way into the court system for drug related crimes, instead of penalizing them in vain with time in jail and other penalties. It is proven to be more successful to deal with the trouble of drug addiction more straightforwardly, than to enforce such penalties. The majority of individuals who do not end up in drug and alcohol treatment will often wind back up in the criminal justice system, whilst criminal justice clients in drug rehabilitation generally don't fall back into drug use and have a better chance at staying sober and away from the court system completely.
