The Black Eyed Peas star has revealed that she was "hallucinating on a daily basis" from the killer drug.
“I was [suffering from] chemically-induced psychosis and dementia. I was hallucinating on a daily basis," she told l newspaper.
“It took a year after getting off that drug for the chemicals in my brain to settle so that I stopped seeing things. I’d just be sitting there, seeing a random bee or bunny.”
She added: "The drugs thing, it was a hell of a lot of fun… until it wasn’t. But you know what, I thank the day it happened to me. Because that’s my strength, my faith, my hope for something better."
