I've linked to Faces of Meth before, but I don't think I've linked to quite this version. Chilling. (Note: Two of the thumbnails are crossed with each other, so you click on a woman's face and get larger photos of a man, and vice-versa, but only two.)
Random note: Last time I posted a meth link, I apparently got listed for "meth" in Google or something, because a ton of people who'd obviously never read PCJM before found the site and started posting testimonies about what a scourge meth was and how hard it was for them (or their children) to kick it. Not that there's anything wrong with kicking meth, but I'm certainly not used to that kind of comment on this site, where the most serious thing discussed is what episode of "Facts of Life" was the best. It was just like...changing the channel from a TV Funhouse episode to a PBS docudrama.
