A jail deputy in Oregon started collecting before and after mug shots of meth uses, calling them “The Faces of Meth.” It’s pretty scary stuff, how terribly and completely changed these people’s faces and bodies are. (Now, there’s one pair in there where I think the person looks better in the second shot, but that’s just me. Most of them are seriously horrifying. Work-safe, except if you work in a meth lab.)
I had a friend who did a lot of crystal meth. Said it was great, because it allowed him to concentrate for days at a stretch. (Concentrating mostly on doing more crystal meth, or clubbing, or whatever else he was doing, but he ostensibly used it to get lots of work done too.) I haven’t seen him in years. I heard a while back he didn’t look so good. He once said he wanted to get a Ritalin prescription, because that would have the same effect on him…and it wouldn’t be illegal.
