Criminal justice clients are a significant portion of clientele who are currently taking part in alcohol and drug treatment programs in Sims and in the USA. Judicial systems in the country often find it more effective to rehab people who have ended up in the court system for drug related crimes, rather than penalizing them to no avail with time in jail and other such rulings. It is proven to be more effective to tackle the issue of addiction directly, rather than enforce these sorts of penalties. Most who do not wind up in drug and alcohol treatment will frequently wind back up in the criminal justice hamster wheel, while criminal justice clients in alcohol and drug 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.
