MARK ARM : Even if I did talk to [Layne Staley], I don’t know what I would have said. Seeing him so far down the line on this trajectory that he had set for himself made me queasy. It seemed to me like once he discovered heroin, he decided he was going to fully embrace it. Based on the songs on Dirt, he just jumped in. There was no turning back. It was unfortunate and pathetic. That was the myth he made for himself, and he was living it out.
