Interesting article.

As someone who has followed the Landis scandal, and been around urinalysis drug screens (UAs) to the point of discussing the procedures with experts, seen how the samples are handled (more carefully than donated blood), and heard almost every excuse known to modern man (there's a few in the article I've never heard), I have far, far more faith in them than excuses.

As I used to say, YOU have a reason to lie. The lab doesn't. Let's look historically - have YOU ever lied about your drug use? Who would you believe? I'd really like to believe you, and I'm suspecting you almost believe you, and if what you're telling me is true, I'd have to throw out every UA drug screen we've ever done.

Etc.
