Criminal justice clients are a considerable percentage of clients who are currently taking part in alcohol and drug treatment programs in Colliers and in the USA. Judges in the U.S. often find it more effective to rehabilitate people who have found their way into 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 handle the problem of drug or alcohol addiction directly, rather than enforce such penalties. Most who do not wind up in alcohol and drug rehab will often turn right back up in the criminal justice system, while criminal justice clients in alcohol and drug rehab generally don't make the same mistakes and have a better chance at staying sober and away from the court system entirely.
