Criminal justice clients are a considerable portion of clients who take part in alcohol and drug rehab facilities in Charlestown and across the nation. Court systems in the U.S. are finding it more effective to treat individuals who have ended up in the criminal justice system for drug related crimes, instead of penalizing them in vain with jail time and other penalties. It has proven more helpful to tackle the problem of drug or alcohol addiction more straightforwardly, than to enforce such penalties. The majority of individuals who do not make their way to drug rehab will often wind back up in the criminal justice hamster wheel, while criminal justice clients in alcohol and drug treatment generally don't fall back into drug use and have a better chance at remaining sober and out of the court system entirely.
