I’m like, f*ck no. If I’d been clean and sober, I wouldn’t be Ozzy. If I’d done normal, sensible things, I wouldn’t be Ozzy… Look, if it ends tomorrow, I can’t complain. I’ve been all around the world. Seen a lot of things. I’ve done good… and I’ve done bad. But right now, I’m not ready to go anywhere.”Last Rites will be available as an audiobook, ebook, and hardcover book starting October 7, 2025. This is not the Black Sabbath singer's first memoir, given that he penned "I Am Ozzy" in 2010, which ranked No. 2 on The New York Times bestseller list.

He started trying to get clean in 1984 and finally turned sober around 2014 after several attempts. During a 2021 interview with Variety, the singer reflected on his addiction and said:"I thought I'd be drinking to the day I die. Most of the people that I drank with are dead. And the ones that aren't, that still continue to drink, are going to be dead soon. It's not a happy ending. If you want to carry on drinking, my hat goes off to you."During an episode of The Osbournes podcast dated October 2024, Ozzy Osbourne talked to Billy Morrison about microdosing, citing that he went to a doctor since one of his friends started to use ketamine. On asking the doctor to administer a tiny bit of ketamine, Osbourne realised "that was enough to spark" him.Putting forth his stance to not resort to microdosing, Osbourne said:"For me, that's lighting the fuse. The old saying in the program is that's what I stick my life; one's too many and 10's not enough thousand never enough."Despite being diagnosed with Parkinson's in 2003, undergoing multiple surgeries for a quad bike accident, and battling addiction over the years, Ozzy Osbourne left a long-lasting impression on his fans with his final concert on July 5, 2025, in front of 40,000 attendees at Villa Park, Birmingham.
