Criminal justice clients are a significant percentage of clientele who take part in alcohol and drug rehabilitation programs in South Wales and in the USA. Judicial systems around the country often find it more helpful to rehab people who have wound up in the criminal justice system for drug related crimes, rather than punishing them in vain with jail time and other such rulings. It has proven more effective to tackle the trouble of addiction directly, rather than enforce such penalties. Most individuals who do not wind up in alcohol and drug treatment will often wind back up in the criminal justice hamster wheel, while criminal justice clients in drug rehab generally don't fall back into drug use and have a better chance at staying sober and away from the court system completely.
