Criminal justice clients are a large percentage of clients who take part in alcohol and drug rehab centers in Vanderbilt and in the USA. Judicial systems around the country often find it more helpful to rehabilitate men and women who have wound up in the criminal justice system for crimes relating to drugs, instead of penalizing them to no avail with jail time and other penalties. It is proven to be more successful to tackle the problem of addiction more straightforwardly, than to invoke these sorts of penalties. Most who do not end up in alcohol and drug rehab will frequently wind back up in the criminal justice hamster wheel, while criminal justice clients in alcohol and drug treatment often don't make the same mistakes and have a better chance at remaining abstinent and out of the court system completely.
