Poor Johnny had one of the worst deaths I can imagine.
He was given a bunch of LSD by some shitheads, thinking it was something else. Way more than anyone would possibly take consciously (remember just a tiny drop on blotter paper is enough to trip for 8 hours). So he didn't know wtf was going on with him and thought taking the Methadone he had would calm him down. He couldn't get the high down and apparently OD'ed on the Methadone. He was found dead curled up like a baby and under some furniture..like he just crawled in there and went through hell.
