Criminal justice clients are a significant percentage of clientele who are currently taking part in alcohol and drug treatment centers in Serena, IL. and in the USA. Court systems in the U.S. often find it more advantageous to rehab people who have found their way into the criminal justice system for drug related crimes, rather than penalizing them in vain with time in jail and other penalties. It has proven more effective to deal with the issue of drug addiction directly, rather than enforce such penalties. Most who do not end up in alcohol and drug rehabilitation will often turn right back up in the criminal justice system, whilst criminal justice clients in drug rehab often don't fall back into drug use and have a much better chance at remaining sober and away from the court system entirely.
