Criminal justice clients are a large portion of clientele who take part in alcohol and drug treatment centers in Waterloo and in the USA. Judicial systems in the U.S. often find it more effective to rehabilitate men and women who have wound up in the court system for drug related crimes, rather than punishing them to no avail with time in jail and other penalties. It is proven to be more successful to deal with the issue of drug addiction directly, than to invoke these sorts of penalties. The majority of who do not wind up in drug and alcohol rehab will frequently turn right back up in the criminal justice hamster wheel, whilst criminal justice clients in alcohol and drug rehab generally don't make the same mistakes and have a better chance at remaining sober and away from the court system for good.
