Did you look at the referenced research? The newest info is from 2002...six years ago! Most of the references are almost 10 years old. Picture the kindbud that you had 6 or 10 years ago vs today. I referenced the same article about a month ago. While it is completely wrong if the drug courts consider it valid....it isn't current research. It's a rehash of out of date information. That's my understanding...but I'm thankfully not an expert when it comes to the court system.
