I think that’s what happened the Harry Nilsson. I loved his music but he was a druggie and burned out way before his time. He began anti-gun when his friend John Lennon was shot. I think he actually make anti-gun commercials.
It has been my personal observation that drugs-legal or illegal-catch up with and burn a person out years before they would have checked out otherwise-two of my relatives were addicted to prescription drugs-both OD’d in their 60’s-in a family in which living into the 90’s is common. Small wonder the rest of us regard drugs as poison to be avoided.
Nilsson, Johnny Cash, Reed, one of the Gibb brothers, and most of the other musicians who died untimely had used drugs for some years in the past-besides the aforementioned relatives, several friends of mine who’d been users have died in their early 50’s to mid 60’s. Most of them had quit all drugs years before, but their bodies were already trashed.
