Criminal justice clients are a large percentage of clients who are currently taking part in alcohol and drug rehabilitation centers in Peck and in the USA. Court systems in the U.S. often find it more advantageous to rehabilitate men and women who have wound up in the criminal justice system for drug related crimes, instead of punishing them to no avail with jail time and other penalties. It has proven more effective to tackle the issue of addiction more straightforwardly, rather than invoke these sorts of penalties. The majority of individuals who do not make their way to drug treatment will often wind back up in the criminal justice hamster wheel, whilst criminal justice clients in drug treatment often don't fall back into drug use and have a better chance at remaining sober and away from the court system completely.
