Sugar Ray's Mark McGrathsaid that Weiland was "romanced by the whole idea of addiction" in an interview on the Allegedly podcast earlier this week.

"He told me, himself!" McGrath said of his friend. "It was more the routine of shooting up and copping and all that, as well. It was the lifestyle and all his heroes did -- it was Iggy Pop, or Johnny Thunders. He lived it. He was a real dynamic and true artist in all the sense and unfortunately sometimes that's part of the package."

"It's the old cliche, you can't help someone who doesn't want to help himself."

Weiland's ex-wife and the mother of his two children also issued a strongly-worded open letter via Rolling Stone, in which she begged music fans not to glamorize addiction.

"So many people have been gracious enough to praise his gift. The music is here to stay," Mary Forsberg Weiland wrote. "But at some point, someone needs to step up and point out that yes, this will happen again -- because as a society we almost encourage it. We read awful show reviews, watch videos of artists falling down, unable to recall their lyrics streaming on a teleprompter just a few feet away. And then we click 'add to cart' because what actually belongs in a hospital is now considered art."
