I think I've got some more insight on this subject for us folks.
Some of you may remember that I did live in Seattle back in 93 to late 95(about one year and a half), and while I was there I bumped into every member of Alice in Chains except Layne Staley, infact I meet Jerry Cantrell and then bass player Mike Inez three times, but never saw Layne! The band I was in at the time(Illicit Smile) almost started renting rehearsals spaces from a company called NAFT agencies, ran by Mark Naft(kinda looks like a chubby Tom Araya), nice guy too. Anyhow, Mark Naft use to fund Alice in Chains back in the day before they were signed, infact, you can see Mark Nafts name on the thank you lists in most of their albums. I remember one time we were down at Nafacy productions(mark invited us to a party), Alica in Chains was there rehearsing(ofcourse nobody was allowed to see me) but you could hear them rehearsing and I remember Mark coming up to me and saying, "Hey guys, enjoy the barbeque and the beer, me and the boys are going over to Laynes house to wish him happy birthday! I couldn't believe it, the guy didn't even want to go out on his birthday! I guess my point of this story is that poor Layne was not only a bad bad bad junkie, but he was a junkie for along time as well! I certainly agree with Gregadeth overall, it's like Layne didn't even want any help. By my math he was a junkie for more than 10 years before it killed him! Overall, it's a incredible shame that Layne couldn't break the habbit but at the same time, I know that the rest of Alice in Chains were constantly trying to help him, he didn't seem to want it.
