Criminal justice clients are a significant percentage of clientele who are currently taking part in drug and alcohol treatment facilities in Nantucket, MA. and in the USA. Court systems in the U.S. are finding it more helpful to rehab people who have found their way into the criminal justice system for crimes relating to drugs, rather than penalizing them in vain with time in jail and other such rulings. It is proven to be more effective to tackle the issue of drug or alcohol addiction directly, than to invoke such penalties. Most who do not end up in alcohol and drug rehab will typically wind back up in the criminal justice system, whilst criminal justice clients in drug and alcohol treatment often don't fall back into drug use and have a better chance at remaining abstinent and out of the court system for good.
