Ozzy Osbourne says a horse set him straight on the dangers of taking acid.
In an interview with Classic Rock magazine, he says, "[In the '70s] in America, people were very fond of lacing your drinks with acid. I didn’t care.
“I used to swallow handfuls of tabs at a time. The end of it came when we got back to England.
“I took 10 tabs of acid then went for a walk in a field. I ended up standing there talking to this horse for about an hour.
“In the end the horse turned round and told me to f*** off. That was it for me.”
And bassist Geezer Butler onetime he saw Ozzy take acid and then go for a swim in the ocean.
"At least he thought he did, but he was still on the beach, flailing away in the sand.”
Ozzy's drug use is well known, but to show how addicted he was, he says he "used to get a piece of wood and whack myself over the head, so they would give me a bottle of pain pills."
The one good side, Ozzy says taking drugs helped him get a good night's sleep.
"You do not have to think about going to sleep. You close your eyes and you're done."
Ozzy will release his new album, Patient Number 9, on September 9th.
