Lady Gaga was smoking as many as 15 joints a day to help relieve the pain of a hip injury before a friend made her abruptly quit marijuana, the flamboyant pop singer says in an interview in British gay magazine Attitude.
The singer had what she had said was a "huge breakage" in her right hip earlier this year that forced her to cancel about two dozen concerts and undergo surgery.
"I was smoking 15 joints a day. No tobacco. A day," the magazine reported Lady Gaga as saying in the interview.
"I was just numbing, numbing, numbing myself and then sleeping it off and then getting on stage, killing it in pain, then getting off and smoking, smoking, smoking, not knowing what the pain was."
The singer said that her friend, the performance artist Marina Abramovic, had effectively forced her to stop.
"It wasn't until I was with Marina and she said, 'Okay you're coming to my house, no television, no computer, no marijuana, no nothing, no food. For three days, art only. You eat only art," Lady Gaga said.
"I cold-turkeyed. For weeks and weeks I didn't smoke at all. And now I smoke a little bit at night, just for fun – but not to cope. Marina was the only person who could get me to do that and it was not rehab."
