Criminal justice clients are a considerable portion of clients who are currently taking part in drug rehabilitation programs in Melvin, Iowa and in the USA. Court systems in the U.S. often find it more advantageous to rehabilitate individuals who have ended up in the court system for drug related crimes, instead of punishing them to no avail with time in jail and other penalties. It has proven more effective to tackle the trouble of drug or alcohol addiction directly, than to enforce such penalties. Most individuals who do not end up in drug and alcohol rehabilitation will often wind back up in the criminal justice hamster wheel, while criminal justice clients in drug rehabilitation generally don't fall back into drug use and have a far better chance at remaining sober and away from the court system for good.
