Criminal justice clients are a considerable portion of clientele who take part in alcohol and drug rehabilitation programs in Marvel and in the USA. Court systems in the U.S. often find it more helpful to treat people who have found their way into the court system for drug related crimes, instead of punishing them to no avail with time in jail and other penalties. It has proven more helpful to tackle the problem of addiction directly, rather than enforce such penalties. The majority of individuals who do not make their way to alcohol and drug treatment will often turn right back up in the criminal justice hamster wheel, whilst criminal justice clients in alcohol and drug rehabilitation generally don't make the same mistakes and have a much better chance at staying sober and out of the court system entirely.
