Criminal justice clients are a significant portion of clientele who are currently taking part in drug rehabilitation programs in Concord, Massachusetts and in the USA. Court systems in the U.S. are finding it more effective to treat individuals who have wound up in the court system for crimes relating to drugs, rather than punishing them to no avail with jail time and other penalties. It is proven to be more effective to deal with the trouble of drug addiction directly, rather than invoke such penalties. Most individuals who do not wind up in drug and alcohol rehabilitation will frequently turn right back up in the criminal justice system, whilst criminal justice clients in drug and alcohol rehabilitation often don't make the same mistakes and have a far better chance at staying sober and away from the court system for good.
