Criminal justice clients are a significant portion of clients who are currently taking part in drug rehab centers in University Park, Iowa and in the USA. Court systems around the country are finding it more beneficial to rehabilitate people who have wound up in the court system for drug related crimes, rather than penalizing them in vain with time in jail and other such rulings. It has proven more effective to address the issue of drug addiction directly, than to invoke these sorts of penalties. The majority of who do not end up in alcohol and drug treatment will typically wind back up in the criminal justice system, while criminal justice clients in drug treatment frequently don't fall back into drug use and have a better chance at staying sober and away from the court system entirely.
