Criminal justice clients are a significant percentage of clients who are currently taking part in drug and alcohol rehabilitation programs in Canadensis, Pennsylvania and in the USA. Court systems in the U.S. often find it more helpful to rehabilitate people who have wound up in the criminal justice system for drug related crimes, rather than punishing them in vain with time in jail and other such rulings. It has proven more successful to address the trouble of drug addiction more straightforwardly, than to invoke such penalties. The majority of who do not make their way to alcohol and drug rehab will typically wind back up in the criminal justice system, whilst criminal justice clients in alcohol and drug treatment generally don't make the same mistakes and have a far better chance at remaining sober and out of the court system completely.
