I ran into a guy I worked with about ten years ago when the Wife and I stopped at a convenience store for cold drinks. He had spent some time in prison for being a meth cook and distributor. He'd been out for a few years by the time I was working with him.
One day, he got flash burn on one of his nipples because he was welding with a huge hole in his shirt. That night, when he got home, he took some of his Wife's pain pills. The next day, when he got to work, he went to medcor, our on sight med. care unit. He had to take a piss test and that's the last I ever saw of him.
In the years after his dismissal, I'd heard that he went back to cooking meth. Within a half a second of seeing him, I knew those rumors were true. His eyes were sunken into his head and to be honest, it looked like his head had shrunken. I was sickened by the sight of him.
