Criminal justice clients are a large percentage of clients who take part in alcohol and drug rehab programs in Holyoke and in the USA. Judicial systems in the U.S. often find it more advantageous to rehab individuals who have wound up in the court system for drug related crimes, instead of penalizing them to no avail with time in jail and other penalties. It has proven more successful to address the problem of drug or alcohol addiction more straightforwardly, than to invoke these sorts of penalties. Most individuals who do not end up in alcohol and drug treatment will often wind back up in the criminal justice system, while criminal justice clients in alcohol and drug rehabilitation often don't make the same mistakes and have a much better chance at staying sober and away from the court system for good.
