One of the officers on my forum called it crackX10. It's highly addictive. And the sores on the faces of the people are from some of the crystals coming to the surface of the skin. Here's a few pages to show how people changed from using it. Meth labs are very dangerous, too. They have had explosions from them before from all the chemicals that are used to make it.

Here's a video. My computer won't play it here at work so I don't know what's on it. It's supposed to show the effects of Meth.
