The performer also said in the interview she was “off the rails” at the time and had previously “dropped out of high school”.
Mum of two Pink added: “I was a punk. I had a mouth. I had a chip on my shoulder. Basically, I grew up in a house where every day my parents were screaming at each other, throwing things. They hated each other.
“I got into drugs. I was selling drugs.”
Weeks after her overdose, Pink signed to LaFace Records while still in her teens with girl group Choice as “token white girls on a black label”.
The band was short-lived and by 2000 Pink had launched her solo career.
She first confessed she had suffered an overdose while speaking to Entertainment Weekly in 2012 but said at the time it “wasn’t to the point of going to the hospital”.
Pink added she had been on “all” the “club drugs” and was “a hardcore partyer” from the ages of 12 to 15.
A year before her overdose shock, her friend Sekou Harris suffered a fatal overdose and was killed by heroin when they were both 14.
Pink said she “never took drugs again, ever” after her own near-death experience, adding: “That’s the thing with me. Once I make up my mind, I’m done.”
Pink also said she wielded a “metaphorical machete” with her as a child which made her a “really difficult kid”.
But she said her attitude turned her into a “survivor” and helped her to success in the music industry.
She said: “I never got a record deal because I was cute. I got a record deal because I was fiery, I had a lot to say and I had a voice.”
