Criminal justice clients are a large portion of clients who take part in drug and alcohol rehabilitation facilities in Paris and in the USA. Judges in the U.S. often find it more beneficial to treat people who have ended up in the criminal justice system for crimes relating to drugs, instead of punishing them in vain with jail time and other penalties. It has proven more effective to address the issue of drug or alcohol addiction directly, than to enforce these sorts of penalties. The majority of who do not wind up in drug rehab will typically wind back up in the criminal justice system, while criminal justice clients in alcohol and drug rehab often don't fall back into drug use and have a much better chance at staying abstinent and out of the court system for good.
